ITEM 1. REPORTS TO STOCKHOLDERS.



FUND EXPENSES
- --------------------------------------------------------------------------------

FUND EXPENSES. As a shareholder of the Trust, you incur ongoing costs, including
management fees; service fees; and other Trust expenses. These examples are
intended to help you understand your ongoing costs (in dollars) of investing in
the Trust and to compare these costs with the ongoing costs of investing in
other mutual funds.

The examples are based on an investment of $1,000.00 invested at the beginning
of the period and held for the entire 6-month period ended June 30, 2005.

ACTUAL EXPENSES. The "actual" lines of the table provide information about
actual account values and actual expenses. You may use the information on this
line, together with the amount you invested, to estimate the expense that you
paid over the period. Simply divide your account value by $1,000.00 (for
example, an $8,600.00 account value divided by $1,000.00 = 8.60), then multiply
the result by the number in the "actual" line under the heading entitled
"Expenses Paid During Period" to estimate the expenses you paid on your account
during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES. The "hypothetical" lines of the
table provide information about hypothetical account values and hypothetical
expenses based on the Trust's actual expense ratio, and an assumed rate of
return of 5% per year before expenses, which is not the Trust's actual return.
The hypothetical account values and expenses may not be used to estimate the
actual ending account balance or expenses you paid for the period. You may use
this information to compare the ongoing costs of investing in the Trust and
other funds. To do so, compare this 5% hypothetical example for the class of
shares you hold with the 5% hypothetical examples that appear in the shareholder
reports of the other funds.

Hypothetical assumes 5% annual return before expenses.

Expenses are equal to the Trust's annualized expense, multiplied by the average
account value over the period, multiplied by 181/365 (to reflect the one-half
year period). The annualized expense ratio based on the 6-month period ended
June 30, 2005 is as follows:

NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
1. SIGNIFICANT ACCOUNTING POLICIES

Centennial Government Trust (the Trust) is registered under the Investment
Company Act of 1940, as amended, as an open-end management investment company.
The Trust's investment objective is to seek a high level of current income that
is consistent with the preservation of capital and the maintenance of liquidity.
The Trust's investment advisor is Centennial Asset Management Corporation (the
Manager), a subsidiary of OppenheimerFunds, Inc. (OFI).

     The following is a summary of significant accounting policies consistently
followed by the Trust.

- --------------------------------------------------------------------------------
SECURITIES VALUATION. The net asset value of shares of the Trust is normally
determined twice each day, at 12:00 Noon Eastern time and at 4:00 P.M. Eastern
time on each day The New York Stock Exchange (the Exchange) is open for trading.
Portfolio securities are valued on the basis of amortized cost, which
approximates market value.

- --------------------------------------------------------------------------------
REPURCHASE AGREEMENTS. The Trust requires its custodian bank to take possession,
to have legally segregated in the Federal Reserve Book Entry System or to have
segregated within the custodian's vault, all securities held as collateral for
repurchase agreements. The market value of the underlying securities is required
to be at least 102% of the resale price at the time of purchase. If the seller
of the agreement defaults and the value of the collateral declines, or if the
seller enters an insolvency proceeding, realization of the value of the
collateral by the Trust may be delayed or limited.

- --------------------------------------------------------------------------------
FEDERAL TAXES. The Trust intends to comply with provisions of the Internal
Revenue Code applicable to regulated investment companies and to distribute
substantially all of its investment company taxable income to shareholders,
therefore, no federal income or excise tax provision is required.

The tax components of capital shown in the table below represent distribution
requirements the Trust must satisfy under the income tax regulations, losses the
Trust may be able to offset against income and gains realized in future years
for federal income tax purposes.

            UNDISTRIBUTED NET      UNDISTRIBUTED        ACCUMULATED LOSS
            INVESTMENT INCOME    LONG-TERM GAINS      CARRYFORWARD 1,2,3
            ------------------------------------------------------------
            $ 900,228                       $ --                 $ 4,147

1. As of June 30, 2005, the Trust had $3,383 of net capital loss carryforwards
available to offset future realized capital gains, if any, and thereby reduce
future taxable gain distributions. As of June 30, 2005 details of the capital
loss carryforwards were as follows:

                            EXPIRING
                            -----------------------
                            2012            $ 2,557
                            2013                826
                                            -------
                            Total           $ 3,383
                                            =======

2. During the fiscal years ended June 30, 2005 and June 30, 2004, the Trust did
not utilize any capital loss carryforwards.

3. As of June 30, 2005, the Trust had $764 of post-October losses available to
offset future realized capital gains, if any. Such losses, if unutilized, will
expire in 2014.


                        12 | CENTENNIAL GOVERNMENT TRUST



Net investment income (loss) and net realized gain (loss) may differ for
financial statement and tax purposes. The character of dividends and
distributions made during the fiscal year from net investment income or net
realized gains may differ from their ultimate characterization for federal
income tax purposes. Also, due to timing of dividends and distributions, the
fiscal year in which amounts are distributed may differ from the fiscal year in
which the income or net realized gain was recorded by the Trust.

     The tax character of distributions paid during the years ended June 30,
2005 and June 30, 2004 were as follows:

                                          YEAR ENDED      YEAR ENDED
                                       JUNE 30, 2005   JUNE 30, 2004
            --------------------------------------------------------
            Distributions paid from:
            Ordinary income             $ 19,140,213     $ 7,971,873

- --------------------------------------------------------------------------------
TRUSTEES' COMPENSATION. The Board of Trustees has adopted a deferred
compensation plan for independent trustees that enables trustees to elect to
defer receipt of all or a portion of the annual compensation they are entitled
to receive from the Trust. For purposes of determining the amount owed to the
Trustee under the plan, deferred amounts are treated as though equal dollar
amounts had been invested in shares of the Trust or in other Oppenheimer funds
selected by the Trustee. The Trust purchases shares of the funds selected for
deferral by the Trustee in amounts equal to his or her deemed investment,
resulting in a Trust asset equal to the deferred compensation liability. Such
assets are included as a component of "Other" within the asset section of the
Statement of Assets and Liabilities. Deferral of trustees' fees under the plan
will not affect the net assets of the Trust, and will not materially affect the
Trust's assets, liabilities or net investment income per share. Amounts will be
deferred until distributed in accordance to the Plan.

- --------------------------------------------------------------------------------
DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions to
shareholders, which are determined in accordance with income tax regulations,
are recorded on the ex-dividend date. Income distributions, if any, are declared
daily and paid monthly. Capital gain distributions, if any, are declared and
paid annually but may be paid at other times to maintain the net asset value per
share at $1.00.

- --------------------------------------------------------------------------------
CUSTODIAN FEES. Custodian Fees and Expenses in the Statement of Operations may
include interest expense incurred by the Trust on any cash overdrafts of its
custodian account during the period. Such cash overdrafts may result from the
effects of failed trades in portfolio securities and from cash outflows
resulting from unanticipated shareholder redemption activity. The Trust pays
interest to its custodian on such cash overdrafts at a rate equal to the Federal
Funds Rate plus 0.50%. The Reduction to Custodian Expenses line item, if
applicable, represents earnings on cash balances maintained by the Trust during
the period. Such interest expense and other custodian fees may be paid with
these earnings.

- --------------------------------------------------------------------------------
SECURITY TRANSACTIONS. Security transactions are recorded on the
trade date. Realized gains and losses on securities sold are determined on the
basis of identified cost.

1. SIGNIFICANT ACCOUNTING POLICIES CONTINUED

OTHER. The preparation of financial statements in conformity with U.S. generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of income and expenses during the reporting
period. Actual results could differ from those estimates.

- --------------------------------------------------------------------------------
2. SHARES OF BENEFICIAL INTEREST

The Trust has authorized an unlimited number of no par value shares of
beneficial interest. Transactions in shares of beneficial interest were as

- --------------------------------------------------------------------------------
3. FEES AND OTHER TRANSACTIONS WITH AFFILIATES

MANAGEMENT FEES. Management fees paid to the Manager were in accordance with the
investment advisory agreement with the Trust which provides for a fee at an
annual rate of 0.50% of the first $250 million of the Trust's net assets, 0.475%
of the next $250 million, 0.45% of the next $250 million, 0.425% of the next
$250 million, 0.40% of the next $250 million, 0.375% of the next $250 million

- --------------------------------------------------------------------------------
ADMINISTRATION SERVICES. The Trust pays the Manager a fee of $1,500 per year for
preparing and filing the Trust's tax returns.

- --------------------------------------------------------------------------------
TRANSFER AGENT FEES. Shareholder Services, Inc. (SSI) acts as the transfer and
shareholder servicing agent for the Trust and for other registered investment
companies. The Trust pays SSI a per account fee. For the year ended June 30,
2005, the Trust paid $866,269 to SSI for services to the Trust.

- --------------------------------------------------------------------------------
SERVICE PLAN (12b-1) FEES. The Trust has adopted a service plan. It reimburses
Centennial Asset Management Corporation, the Distributor, for a portion of its
costs incurred for services provided to accounts that hold shares of the Trust.
Reimbursement is made quarterly, or monthly depending on asset size, at an
annual rate of up to 0.20% of the average annual net assets of the Trust. The
Distributor currently uses all of those fees to pay dealers, brokers, banks and
other financial institutions quarterly for providing personal services and
maintenance of accounts of their customers that hold shares of the Trust. Fees
incurred by the Trust under the Plan are detailed in the Statement of
Operations.


                        14 | CENTENNIAL GOVERNMENT TRUST



- --------------------------------------------------------------------------------
WAIVERS AND REIMBURSEMENTS OF EXPENSES. SSI has voluntarily agreed to limit
transfer and shareholder servicing agent fees to 0.35% of average annual net
assets of the Trust. This undertaking may be amended or withdrawn at any time.

- --------------------------------------------------------------------------------
4. ILLIQUID SECURITIES

As of June 30, 2005, investments in securities included issues that are
illiquid. A security may be considered illiquid if it lacks a readily available
market or if its valuation has not changed for a certain period of time. The
Trust will not invest more than 10% of its net assets (determined at the time of
purchase and reviewed periodically) in illiquid securities. Securities that are
illiquid are marked with the applicable footnote on the Statement of
Investments.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
TO THE BOARD OF TRUSTEES AND SHAREHOLDERS OF CENTENNIAL GOVERNMENT TRUST:
We have audited the accompanying statement of assets and liabilities of
Centennial Government Trust, including the statement of investments, as of June
30, 2005, and the related statement of operations for the year then ended, the
statements of changes in net assets for each of the two years in the period then
ended, and the financial highlights for each of the five years in the period
then ended. These financial statements and financial highlights are the
responsibility of the Trust's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

      We conducted our audits in accordance with the standards of the Public
Company Accounting Oversight Board (United States). Those standards require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material misstatement.
The Trust is not required to have, nor were we engaged to perform, an audit of
its internal control over financial reporting. Our audit includes consideration
of internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the Trust's internal control over
financial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of June 30, 2005, by correspondence with the custodian
and brokers; where replies were not received from brokers, we performed other
auditing procedures. We believe that our audits provide a reasonable basis for
our opinion.

      In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of
Centennial Government Trust as of June 30, 2005, the results of its operations
for the year then ended, the changes in its net assets for each of the two years
in the period then ended, and the financial highlights for each of the five
years in the period then ended, in conformity with accounting principles
generally accepted in the United States of America.

BOARD APPROVAL OF THE TRUST'S INVESTMENT
ADVISORY AGREEMENT  UNAUDITED
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
Each year, the Board of Trustees (the "Board"), including a majority of the
independent Trustees, is required to determine whether to renew the Trust's
advisory agreement. The Investment Company Act of 1940, as amended, requires
that the Board request and evaluate, and that the Manager provide, such
information as may be reasonably necessary to evaluate the terms of the advisory
agreement. The Board employs an independent consultant to prepare a report that
provides information, including comparative information, that the Board requests
for this purpose. In addition, the Board receives information throughout the
year regarding Trust services, fees, expenses and performance.

     NATURE AND EXTENT OF SERVICES. In considering the renewal of the Trust's
advisory agreement for the current year, the Board evaluated the nature and
extent of the services provided by the Manager and its affiliates. The Manager
provides the Trust with office space, facilities and equipment; administrative,
accounting, clerical, legal and compliance personnel; securities trading
services; oversight of third party service providers and the services of the
portfolio managers and the Manager's investment team, who provide research,
analysis and other advisory services in regard to the Trust's investments.

     QUALITY OF SERVICES. The Board also considered the quality of the services
provided and the quality of the Manager's resources that are available to the
Trust. The Board noted that the Manager has had over twenty years of experience
as an investment adviser. The Board evaluated the Manager's administrative,
accounting, legal and compliance services and information the Board received
regarding the experience and professional qualifications of the Manager's
personnel and the size and functions of its staff. The Board members also
considered their experiences as directors or trustees of the Trust and other
funds advised by the Manager. The Board received and reviewed information
regarding the quality of services provided by affiliates of the Manager, which
it also reviews at other times during the year in connection with the renewal of
the Trust's service agreements. The Board was aware that there are alternatives
to retaining the Manager.

     PORTFOLIO MANAGEMENT SERVICES AND PERFORMANCE. In its evaluation of the
quality of the portfolio management services to be provided, the Board
considered the experience of Carol E. Wolf and Barry D. Weiss and the Manager's
money market investment team and analysts. The Trust's portfolio is managed by
Ms. Wolf and Mr. Weiss who are primarily responsible for the day-to-day
management of the Trust's investments. Ms. Wolf has been a manager of the
Trust's portfolio since November 1988 and has been a Senior Vice President of
the Manager since June 2000 and of HarbourView Asset Management Corporation
since June 2003. She is an officer of other portfolios in the OppenheimerFunds
complex. Mr. Weiss has been a manager of the Trust's portfolio since August 2001

has been a Vice President of the Manager since July 2001 and of HarbourView
Asset Management Corporation since June 2003. He is also an officer of other
portfolios in the OppenheimerFunds complex. Ms. Wolf has had over twenty years
of experience and Mr. Weiss has had over five years of experience managing money
market investments.

     The Board also reviewed information, prepared by the Manager and by the
independent consultant, comparing the Trust's historical performance to relevant
market indices and to the performance of other U.S. government money market
funds advised by other investment advisers. The Board also receives and reviews
comparative performance information regarding the Trust and other funds at each
Board meeting. The Board noted that the Trust's one-year and ten-year
performance was slightly below its peer group average. However, its three-year
and five-year performance was better than its peer group average.

     MANAGEMENT FEES AND EXPENSES. The Board also reviewed information,
including comparative information, regarding the fees paid to the Manager and
its affiliates and the other expenses borne by the Trust. The independent
consultant provided comparative data in regard to the fees and expenses of the
Trust, other U.S. government money market funds and other funds with comparable
asset levels and distribution features. The Board noted that the Trust's actual
management fees and total expenses are both lower than its peer group average
although its contractual management fees are slightly higher than its peer group
average. In addition, the Board evaluated the comparability of the fees charged
and the services provided to the Trust to the fees charged and services provided
to other types of entities advised by the Manager.

     PROFITABILITY OF THE MANAGER AND AFFILIATES. The Board also reviewed
information regarding the cost of services provided by the Manager and its
affiliates and the Manager's profitability. The Board considered that the
Manager must be able to pay and retain experienced professional personnel at
competitive rates to provide services to the Trust and that maintaining the
financial viability of the Manager is important in order for the Manager to
continue to provide significant services to the Trust and its shareholders. In
addition the Board considered information that was provided regarding the direct
and indirect benefits the Manager receives as a result of its relationship with
the Trust, including compensation paid to the Manager's affiliates.

     ECONOMIES OF SCALE. The Board reviewed the extent to which the Manager may
realize economies of scale in managing and supporting the Trust and the current
level of Trust assets in relation to the Trust's breakpoint schedule for its
management fees. The Board considered that the Trust has not experienced any
recent asset growth and that, based on current asset levels, the Trust has not
passed its last management fee breakpoint.

     CONCLUSIONS. These factors were also considered by the independent Trustees
meeting separately from the full Board, assisted by experienced counsel to the
Trust and to the independent Trustees. Trust counsel and the independent
Trustees' independent of the Manager within the meaning and intent of the
Securities and Exchange Commission Rules.

     Based on its review of the information it received and its evaluations
described above, the Board, including a majority of the independent Trustees,
concluded that the nature, extent and quality of the services provided to the
Trust by the Manager are a benefit to the Trust and in the best interest of the
Trust's shareholders and that the amount and structure of the compensation
received by the Manager and its affiliates are reasonable in relation to the
services provided. Accordingly, the Board elected to continue the advisory
agreement for another year. In arriving at this decision, the Board did not
single out any factor or factors as being more important than others, but
considered all of the factors together. The Board judged the terms and
conditions of the advisory agreement, including the management fee, in light of
all of the surrounding circumstances.

THE FUNDS' GOVERNANCE COMMITTEE PROVISIONS WITH RESPECT TO NOMINATIONS OF
DIRECTORS/TRUSTEES TO THE RESPECTIVE BOARDS

      1.    The Funds' Governance Committee (the "Committee") will evaluate
            potential Board candidates to assess their qualifications. The
            Committee shall have the authority, upon approval of the Board, to
            retain an executive search firm to assist in this effort. The
            Committee may consider recommendations by business and personal
            contacts of current Board members and by executive search firms
            which the Committee may engage from time to time and may also
            consider shareholder recommendations. The Committee may consider
            the advice and recommendation of the Funds' investment manager and
            its affiliates in making the selection.

      2.    The Committee shall screen candidates for Board membership. The
            Committee has not established specific qualifications that it
            believes must be met by a trustee nominee. In evaluating trustee
            nominees, the Committee considers, among other things, an
            individual's background, skills, and experience; whether the
            individual is an "interested person" as defined in the Investment
            Company Act of 1940; and whether the individual would be deemed an
            "audit committee financial expert" within the meaning of applicable
            SEC rules. The Committee also considers whether the individual's
            background, skills, and experience will complement the background,
            skills, and experience of other nominees and will contribute to the
            Board. There are no differences in the manner in which the
            Committee evaluates nominees for trustees based on whether the
            nominee is recommended by a shareholder.

      3.    The Committee may consider nominations from shareholders for the
            Board at such times as the Committee meets to consider new nominees
            for the Board. The Committee shall have the sole discretion to
            determine the candidates to present to the Board and, in such cases
            where required, to



            shareholders. Recommendations for trustee nominees should, at a
            minimum, be accompanied by the following:

                  o     the name, address, and business, educational, and/or
                        other pertinent background of the person being
                        recommended;

                  o     a statement concerning whether the person is an
                        "interested person" as defined in the Investment
                        Company Act of 1940;

                  o     any other information that the Funds would be required
                        to include in a proxy statement concerning the person
                        if he or she was nominated; and

                  o     the name and address of the person submitting the
                        recommendation and, if that person is a shareholder,
                        the period for which that person held Fund shares.

            The recommendation also can include any additional information
            which the person submitting it believes would assist the Committee
            in evaluating the recommendation.

      4.    Shareholders should note that a person who owns securities issued
            by Massachusetts Mutual Life Insurance Company (the parent company
            of the Funds' investment adviser) would be deemed an "interested
            person" under the Investment Company Act of 1940. In addition,
            certain other relationships with Massachusetts Mutual Life
            Insurance Company or its subsidiaries, with registered
            broker-dealers, or with the Funds' outside legal counsel may cause
            a person to be deemed an "interested person."

      5.    Before the Committee decides to nominate an individual as a
            trustee, Committee members and other directors customarily
            interview the individual in person. In addition, the individual
            customarily is asked to complete a detailed questionnaire which is
            designed to elicit information which must be disclosed under SEC
            and stock exchange rules and to determine whether the individual is
            subject to any statutory disqualification from serving as a trustee
            of a registered investment company.

ITEM 11. CONTROLS AND PROCEDURES.

Based on their evaluation of the registrant's disclosure controls and
procedures (as defined in rule 30a-3(c) under the Investment Company Act of
1940 (17 CFR 270.30a-3(c)) as of June 30, 2005, the registrant's principal
executive officer and principal financial officer found the registrant's
disclosure controls and procedures to provide reasonable assurances that
information required to be disclosed by the registrant in the reports that it
files under the Securities Exchange



Act of 1934 (a) is accumulated and communicated to registrant's management,
including its principal executive officer and principal financial officer, to
allow timely decisions regarding required disclosure, and (b) is recorded,
processed, summarized and reported, within the time periods specified in the
rules and forms adopted by the U.S. Securities and Exchange Commission.

There have been no changes in the registrant's internal controls over financial
reporting that occurred during the registrant's second fiscal quarter of the
period covered by this report that has materially affected, or is reasonably
likely to materially affect, the registrant's internal control over financial
reporting.
