         In this prospectus, the words "Century Aluminum," "we," "us," "our" and

         This prospectus is part of a registration statement that we filed with
the Securities and Exchange Commission, or the SEC, using a "shelf" registration

and sell up to $300,000,000 of our common stock and the selling shareholders may
from time to time offer and sell up to an aggregate of 500,000 shares of our
common stock owned by them.

         This prospectus describes our common stock and the general manner in
which we and the selling shareholders will offer our common stock. Each time we
or the selling shareholders offer any common stock under this prospectus, we
will provide a prospectus supplement that will contain specific information
about the terms of that offering. The prospectus supplement may add to or update
other information contained in, or incorporated by reference into, this
prospectus. Before making your investment decision, you should read the

                           FORWARD-LOOKING STATEMENTS

         In this prospectus, together with the documents incorporated by
reference herein, and each prospectus supplement, we make statements that may be
considered forward-looking statements within the meaning of Section 27A of the
Securities Act of 1933, as amended, or the Securities Act, and Section 21E of
the Exchange Act. We have based these forward-looking statements on our current
expectations and projections about future events. Many of these statements may
be identified by the use of forward-looking words such as "anticipate,"
"believe," "hope," "expect," "anticipate," "should," "will," "will likely,"
"forecast," "project," "planned," "estimated" and "potential," among others.
These forward-looking statements are subject to risks, uncertainties and
assumptions including, among other things:

         -        Our high level of indebtedness reduces cash available for
                  other purposes, such as the payment of dividends, and limits
                  our ability to incur additional debt and pursue our growth
                  strategy;

         -        The cyclical nature of the aluminum industry causes
                  variability in our earnings and cash flows;

         -        The loss of a major customer would increase our production
                  costs at those facilities which deliver molten aluminum;

         -        Glencore International AG owns a large percentage of our
                  common stock and has the ability to influence matters
                  requiring shareholder approval;

         -        We could suffer losses due to a temporary or prolonged
                  interruption of the supply of electrical power to our
                  facilities, which can be caused by unusually high demand,
                  blackouts, equipment failure, natural disasters or other
                  catastrophic events;

         -        Due to increasing prices for alumina, the principal raw
                  material used in primary aluminum production, changes to or
                  disruptions in our current alumina supply arrangements would
                  materially impact our raw material costs;

         -        Changes in the relative cost of certain raw materials and
                  energy compared to the price of primary aluminum could affect
                  our margins;

         -        Most of our employees are unionized and any labor dispute or
                  failure to successfully renegotiate an existing labor
                  agreement could materially impair our ability to conduct our
                  production operations at our unionized facilities;

         -        We are subject to a variety of environmental laws that could
                  result in costs or liabilities; and

         -        We may not realize the expected benefits of our growth
                  strategy if we are unable to successfully integrate the
                  businesses we acquire.

         Given these uncertainties, you should not place undue reliance on these
forward-looking statements. Also, these forward-looking statements represent our
estimates and assumptions only as of the date on which they are made.

                                       2



     You should read this prospectus, together with the documents incorporated
by reference herein, and the applicable prospectus supplement completely and
with the understanding that our actual future results may be materially
different from those expressed in our forward-looking statements. We have no
obligation (other than as required by law) to update or revise any of our
forward-looking statements. We qualify all of our forward-looking statements by
these cautionary statements.

                            CENTURY ALUMINUM COMPANY

         We are a leading North American producer of primary aluminum. Our
facilities produce value-added and standard-grade primary aluminum products. We
are the second largest primary aluminum producer in the United States, behind
Alcoa Inc., having produced over 1.1 billion pounds of primary aluminum in 2003
with net sales of $782.5 million.

         We currently own:

         -        the Hawesville facility, located in Hawesville, Kentucky,
                  which began operations in 1970 and has an annual production
                  capacity of 538 million pounds of primary aluminum;

         -        the Ravenswood facility, located in Ravenswood, West Virginia,
                  which began operations in 1957 and has an annual production
                  capacity of 375 million pounds of primary aluminum; and

         -        a 49.7% ownership interest in the Mt. Holly facility, located
                  in Mt. Holly, South Carolina, which began operations in 1980
                  and contributes 243 million pounds to our overall annual
                  production capacity and is operated by Alcoa, which holds the
                  remaining 50.3% ownership interest.

         Our strategic objectives are to grow our aluminum business by pursuing
opportunities to acquire primary aluminum reduction facilities that offer
favorable investment returns and lower our per unit production costs;
diversifying our geographic presence; and pursuing opportunities in bauxite
mining and alumina refining.

         Our principal executive offices are located at 2511 Garden Road,
Building A, Suite 200, Monterey, California 93940. Our telephone number at that
address is (831) 642-9300. You may also obtain additional information about us
from our website, which is located at www.centuryaluminum.com. Information
contained in our website is not incorporated by reference in, and should not be
considered a part of, this prospectus.

                                 USE OF PROCEEDS

         Except as otherwise may be set forth in each prospectus supplement
accompanying this prospectus, we intend to use the net proceeds we receive from
sales of shares of our common stock pursuant to this prospectus for general
corporate purposes, including acquisitions, plant expansions and repayment of
indebtedness. We have filed a Current Report on Form 8-K dated March 16, 2004,
in which we reported that we entered into an agreement with Columbia Ventures
Corporation to purchase up to 100 percent of the shares of Nordural hf, an
Icelandic company that owns and operates a 90,000 metric-ton-per-year (mtpy)
primary aluminum plant at Grundartangi, Iceland. We intend to finance this
acquisition by offering shares under the registration statement of which this
prospectus forms a part. We will not receive any proceeds from the sale of
shares offered by the selling shareholders.

                              SELLING SHAREHOLDERS

         Century Aluminum Employees Retirement Plan and the Century Aluminum of
West Virginia, Inc. Hourly Employees Pension Plan, may from time to time offer
and sell pursuant to this prospectus and the applicable prospectus supplement up
to an aggregate of 500,000 shares of our common stock.

         During the quarter ended December 31, 2002, our board of directors
authorized the contribution of 100,000 shares of our common stock to the
retirement plan and 400,000 shares of our common stock to the pension plan.
Prior to our contribution, the plans owned no shares of our common stock. As of
March 15, 2004, the retirement plan owned 100,000 shares of our common stock,
representing 0.5% of our outstanding shares of common stock, and the pension
plan owned 400,000 shares of our common stock, representing 1.9% of our
outstanding shares of common stock.

                                       3



         The plans hold their assets in trusts formed for the benefit of all of
our salaried employees and the hourly employees of Century Aluminum of West
Virginia, Inc., respectively. The plans are intended to be tax-qualified under
the Internal Revenue Code of 1986, as amended. The plans are funded by our
contributions, which are held for the sole benefit of the plans' participants
and their beneficiaries and to pay proper expenses related to the administration
of the plans.

         The retirement plan and the pension plan are each administered by a
retirement committee established by the board of directors of Century Aluminum
of West Virginia, a direct subsidiary of Century Aluminum Company. The
retirement committee has the responsibility, power and authority to direct the
investment, management and control of plan assets. The retirement committee has
appointed a trustee to act as fiduciary for the purpose of holding the funds and
property of the plans. The trustee acts at the direction of the retirement
committee. The retirement committee is currently comprised of David W. Beckley,
Gerald J. Kitchen, and Daniel J. Krofcheck, each of whom is an executive officer
of Century Aluminum Company.

         The selling shareholders are pension plans subject to the rules of the
Employee Retirement Income Security Act of 1974, as amended, or ERISA. ERISA
provides that sales and exchanges between a plan and parties-in-interest to the
plan are prohibited without an exemption under the rules of ERISA. Each
prospective purchaser should consult with its counsel to satisfy itself that it
is not a party in interest to the selling plans or, if it is, that the ERISA
prohibited transaction rules will not apply.

                          DESCRIPTION OF CAPITAL STOCK

         Our authorized capital stock consists of 50,000,000 shares of common
stock, par value $0.01 per share, and 5,000,000 shares of preferred stock, par
value $0.01 per share. At March 15, 2004, we had outstanding 21,207,467 shares
of our common stock, 1,395,089 shares reserved for issuance upon conversion of
our convertible preferred stock and 1,549,806 shares reserved for issuance upon
the exercise of outstanding stock options and the vesting of outstanding
performance shares and restricted stock awards.

         The following summary description does not purport to be complete and
is qualified in its entirety by reference to the Delaware General Corporation
Law, or DGCL, and our restated certificate of incorporation and amended and
restated bylaws, which are both incorporated by reference as exhibits to the
registration statement of which this prospectus is a part. See "Where You Can
Find More Information." Reference is made to the DGCL, our certificate of
incorporation and our bylaws for a detailed description of the provisions we
have summarized below.

COMMON STOCK

         Holders of our common stock are entitled to one vote for each share
held on all matters submitted to a vote of stockholders, including the election
of directors. Our certificate of incorporation does not provide for cumulative
voting in the election of directors. Accordingly, holders of a majority of the
shares of our common stock entitled to vote in any election of directors may
elect all the directors standing for election. Subject to any preferential
rights of any outstanding series of preferred stock created by our board of
directors, the holders of our common stock are entitled to receive ratably such
dividends, if any, as may be declared from time to time by our board of
directors from funds which are legally available for that purpose. Upon the
liquidation, dissolution or winding up of Century Aluminum, the holders of our
common stock are entitled to receive ratably any of our net assets available
after the payment of all debts and other liabilities and subject to the prior
rights of any outstanding preferred stock. Holders of our common stock have no
preemptive, subscription, redemption or conversion rights. All shares of our
common stock currently outstanding and those to be issued upon the completion of
any offering under a prospectus supplement will be fully paid and nonassessable.
The rights, preferences and privileges of holders of our common stock are
subject to, and may be adversely affected by, the rights of the holders of
shares of any series of our preferred stock which are currently outstanding or
which we may designate and issue in the future.

PREFERRED STOCK

         Under our certificate of incorporation, our board of directors is
authorized to issue up to 5,000,000 shares of preferred stock without any vote
or action by the holders of our common stock. Our board of directors may issue
preferred stock in one or more series and determine for each series the dividend
rights, conversion rights, voting

                                       4



rights, redemption rights, liquidation preferences, sinking fund terms and the
number of shares constituting that series, as well as the designation thereof.
Depending upon the terms of preferred stock established by our board of
directors, any or all of the preferred stock could have preference over the
common stock with respect to dividends and other distributions and upon the
liquidation of Century Aluminum Company. In addition, issuance of any shares of
preferred stock with voting powers may dilute the voting power of the
outstanding common stock.

         Convertible preferred stock

         We issued 500,000 shares of our 8.0% cumulative convertible preferred
stock to an affiliate of Glencore International AG in April 2001 for a cash
purchase price of $25.0 million. The convertible preferred stock has a par value
per share of $0.01 and a liquidation preference of $50 per share. The
convertible preferred stock ranks junior to our 11 3/4% senior secured first
mortgage notes due 2008, borrowings under our $100.0 million senior secured
revolving credit facility, and all of our other existing and future debt
obligations.

         The purchase agreement for the preferred stock contains customary
indemnification provisions. Following is a summary of the principal terms of the
convertible preferred stock.

         -        Dividends. The holders of the convertible preferred stock are
                  entitled to receive fully cumulative cash dividends at the
                  rate of 8.0% per annum per share accruing daily and payable
                  when declared quarterly in arrears.

         -        Optional conversion. Each share of convertible preferred stock
                  may be converted at any time, at the option of the holder,
                  into shares of our common stock, at a price of $17.92, subject
                  to adjustment for stock dividends, stock splits and other
                  specified corporate actions.

         -        Voting rights. The holders of convertible preferred stock have
                  limited voting rights to approve: (1) any action by us which
                  would adversely affect or alter the preferences and special
                  rights of the convertible preferred stock, (2) the
                  authorization of any class of stock ranking senior to, prior
                  to or ranking equally with the convertible preferred stock,
                  and (3) any reorganization or reclassification of our capital
                  stock or merger or consolidation of Century Aluminum.

         -        Optional redemption. After April 2, 2004, we may redeem the
                  convertible preferred stock at our option for cash at a price
                  of $52 per share, plus unpaid dividends to the date of
                  redemption, declining ratably each year thereafter to $50 at
                  the end of the eighth year.

         -        Transferability. Our convertible preferred stock is freely
                  transferable in a private offering or any other transaction
                  which is exempt from, or not subject to, the registration
                  requirements of the Securities Act and any applicable state
                  securities laws.

         -        Limits on common stock dividends and redemptions and
                  dividends. We are prohibited from declaring any cash dividend
                  or making any cash distribution on our common stock, and are
                  generally unable to redeem, purchase or otherwise acquire any
                  of our common stock, until we have paid all dividends on our
                  convertible preferred stock.

CERTAIN PROVISIONS THAT MAY HAVE AN ANTI-TAKEOVER EFFECT

         The provisions of our certificate of incorporation and bylaws and the
DGCL summarized in the following paragraphs may have an anti-takeover effect and
may delay, defer or prevent a tender offer or takeover attempt, including those
attempts that might result in a premium over the market price for the shares
held by our stockholders.

         Issuance of preferred stock. Our certificate of incorporation provides
our board of directors with the authority to issue shares of preferred stock and
to set the voting rights, preferences and other terms thereof.

         Business combinations. In addition to any affirmative vote required by
law, our certificate of incorporation requires either: (1) the approval of a
majority of the disinterested directors, (2) the approval of the holders of at
least two-thirds of the aggregate voting power of the outstanding voting shares
of Century Aluminum, voting as a class, or (3) the satisfaction of certain
minimum price requirements and other procedural requirements, as preconditions
to

                                       5



certain business combinations with, in general, a person who is the
beneficial owner of 10% or more of our outstanding voting stock.

         Classified board. Our certificate of incorporation provides for a
classified board of directors consisting of three classes as nearly equal in
size as is practicable. Each class holds office until the third annual meeting
for election of directors following the election of such class.

         Number of directors; removal; vacancies. Our certificate of
incorporation provides that the number of directors shall not be less than 3 nor
more than 11. The directors shall have the exclusive power and right to set the
exact number of directors within that range from time to time by resolution
adopted by vote of a majority of the entire board of directors. The board can
only be increased over 11 through amendment of our restated certificate of
incorporation which requires a resolution of the board and the affirmative vote
of the holders of at least two-thirds of the aggregate voting power of the
outstanding shares of stock generally entitled to vote, voting as a class.

         Our certificate of incorporation and bylaws further provide that
directors may be removed only for cause and then only by the affirmative vote of
the holders of at least two-thirds of the outstanding shares of stock generally
entitled to vote, voting as a class. In addition, interim vacancies or vacancies
created by an increase in the number of directors may be filled only by a
majority of directors then in office. The foregoing provisions would prevent
stockholders from removing incumbent directors without cause and filling the
resulting vacancies with their own nominees.

         No stockholder action by written consent; special meetings. Our
certificate of incorporation generally provides that stockholder action may be
taken only at an annual or special meeting of stockholders and cannot be taken
by written consent in lieu of a meeting. Our certificate of incorporation and
bylaws also provide that, subject to the rights of the holders of any class or
series of our preferred stock, special meetings of the stockholders may only be
called pursuant to a resolution adopted by a majority of the board of directors
or the executive committee. Stockholders are not permitted to call a special
meeting or to require the board or executive committee to call a special meeting
of stockholders. Any call for a meeting must specify the matters to be acted
upon at the meeting. Stockholders are not permitted to submit additional matters
or proposals for consideration at any special meeting.

         Stockholder proposals. The bylaws establish an advance notice procedure
for nominations (other than by or at the direction of our board of directors) of
candidates for election as directors at, and for proposals to be brought before,
an annual meeting of stockholders. Subject to any other applicable requirements,
the only business that may be conducted at an annual meeting is that which has
been brought before the meeting by, or at the direction of, the board or by a
stockholder who has given to the secretary of Century Aluminum timely written
notice, in proper form, of the stockholder's intention to bring that business
before the meeting. In addition, only persons who are nominated by, or at the
direction of, the board, or who are nominated by a stockholder who has given
timely written notice, in proper form, to the secretary prior to a meeting at
which directors are to be elected, will be eligible for election as directors.

         Amendment of certain certificate provisions or bylaws. Our certificate
of incorporation requires the affirmative vote of the holders of at least
two-thirds of the aggregate voting power of the outstanding shares of our stock,
voting as a class, generally entitled to vote to amend the foregoing provisions
of our certificate of incorporation and the bylaws.

         Section 203 of the DGCL. We are subject to Section 203 of the DGCL,
which generally prohibits a publicly-held Delaware corporation from engaging in
a "business combination" with an "interested stockholder" for a period of three
years after the date of the transaction in which the person became an interested
stockholder, unless: (1) prior to such date the board of directors of the
corporation approved either the business combination or the transaction in which
the person became an interested stockholder, (2) upon consummation of the
transaction that resulted in the stockholder becoming an interested stockholder,
the interested stockholder owned at least 85% of the outstanding stock of the
corporation, excluding shares owned by directors who are also officers of the
corporation and shares owned by certain employee stock plans, or (3) on or after
such date the business combination is approved by the board of directors of the
corporation and by the affirmative vote of at least two-thirds of the
outstanding voting stock of the corporation that is not owned by the interested
stockholder. A "business combination" generally includes mergers, asset sales
and similar transactions between the corporation and the interested stockholder,
and other

                                       6



transactions resulting in a financial benefit to the interested stockholder. An
"interested stockholder" is a person who, together with affiliates and
associates, owns 15% or more of the corporation's voting stock or who is an
affiliate or associate of the corporation and, together with his affiliates and
associates, has owned 15% or more of the corporation's voting stock within three
years.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Century Aluminum Company is a Delaware corporation. In accordance with
Section 102(b)(7) of the Delaware General Corporation Law (the "DGCL"), the
restated certificate of incorporation of Century Aluminum Company contains a
provision to limit the personal liability of our directors for violations of
their fiduciary duties. This provision eliminates each director's liability to
Century Aluminum Company or its stockholders for monetary damages for breach of
fiduciary duties as a director, except for liability: (i) for any breach of the
director's duty of loyalty to Century Aluminum Company or its stockholders, (ii)
for acts or omissions not in good faith or which involve intentional misconduct
or a knowing violation of law, (iii) under Section 174 of the DGCL providing for
liability of directors for unlawful payment of dividends or unlawful stock
purchase or redemption, or (iv) for any transaction from which the director
derived an improper personal benefit. The effect of this provision is to
eliminate the personal liability of directors for monetary damages for actions
involving a breach of their fiduciary duty of care, including such actions
involving gross negligence.

         Section 145 of the DGCL provides that a corporation may indemnify any
person, including officers and directors, who are, or are threatened to be made,
parties to any threatened, pending or completed legal action, suit or
proceeding, whether civil, criminal, administrative or investigative (other than
an action by or in the right of such corporation), by reason of the fact that
such person was an officer, director, employee or agent of such corporation, or
is or was serving at the request of such corporation as a director, officer,
employee or agent of such corporation, as a director, officer, employee or agent
of another corporation. The indemnity may include expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by such person in connection with such action, suit or proceeding,
provided such officer director, employee or agent acted in good faith and in a
manner he reasonably believed to be in or not opposed to the corporation's best
interests and, for criminal proceedings, had no reasonable cause to believe that
his conduct was unlawful. A Delaware corporation may indemnify officers and
directors in an action by or in the right of the corporation under the same
conditions, except that no indemnification is permitted without judicial
approval if the officer or director is adjudged to be liable to the corporation.
Where an officer or director is successful on the merits or otherwise in defense
of any action referred to above, the corporation must indemnify him against the
expenses which such officer or director actually

                                      II-1



or reasonably incurred. The restated certificate of incorporation for Century
Aluminum Company provides for indemnification to fullest extent permitted by
Section 145 of the DGCL of all persons who we have the power to indemnify under
such section. The restated by-laws for Century Aluminum Company provide for
indemnification of officers and directors to the fullest extent permitted by the
DGCL.

         In addition, we maintain officers' and directors' liability insurance
which insures against liabilities that our officers and directors may incur in
such capacities.

ITEM 17. UNDERTAKINGS.

         The undersigned registrant hereby undertakes:

                  (1) To file, during any period in which offers or sales are
         being made, a post-effective amendment to this registration statement:


                           (i) to include any prospectus required by Section
                  10(a)(3) of the Securities Act of 1933;

                           (ii) to reflect in the prospectus any facts or events
                  arising after the effective date of the registration statement
                  (or the most recent post-effective amendment thereof) which,
                  individually or in the aggregate, represent a fundamental
                  change in the information set forth in the registration
                  statement. Notwithstanding the foregoing, any increase or
                  decrease in volume of securities offered (if the total dollar
                  value of securities offered would not exceed that which was
                  registered) and any deviation from the low or high end of the
                  estimated maximum offering range may be reflected in the form
                  of prospectus filed with the SEC pursuant to Rule 424(b) if,
                  in the aggregate, the changes in volume and price represent no
                  more than a 20% change in the maximum aggregate offering price
                  set forth in the "Calculation of Registration Fee" table in
                  the effective registration statement;

                           (iii) to include any material information with
                  respect to the plan of distribution not previously disclosed
                  in the registration statement or any material change to such
                  information in the registration statement;

         provided, however, that paragraphs (l)(i) and (l)(ii) do not apply if
         the information required to be included in a post-effective amendment
         by those paragraphs is contained in periodic reports filed by the
         registrant pursuant to

                                      II-2



         Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that
         are incorporated by reference in the registration statement;

                  (2) That, for the purpose of determining any liability under
         the Securities Act of 1933, each such post-effective amendment shall be
         deemed to be a new registration statement relating to the securities
         offered therein, and the offering of such securities at that time shall
         be deemed to be the initial bona fide offering thereof; and


                  (3) To remove from registration by means of a post-effective
         amendment any of the securities being registered which remain unsold at
         the termination of the offering.

         The undersigned registrant further undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the SEC such indemnification
is against public policy as expressed in the Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the registrant of expenses incurred or
paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
