LETTER TO SHAREHOLDERS

Dear Shareholder:

We are pleased to present this annual report for Dreyfus Institutional Preferred
Money  Market  Fund.  During  the 12-month reporting period that ended March 31,
2000,  the  fund  produced an annualized yield of 5.34%. Taking into account the
effect of compounding, the fund's annualized effective yield was 5.47%.(1)

The Economy

The  12-month reporting period was characterized by rising interest rates, which
were  primarily  the  result of robust U.S. economic growth and actions taken by
the  Federal  Reserve  Board' s  Open Market Committee toward a more restrictive
monetary    policy.

When  the  reporting  period began on April 1, 1999, the performance of the U.S.
economy  was  showing  signs  of  renewed  strength in the wake of 1998's global
financial  crisis.  Gross  Domestic  Product  (GDP)  had grown at a rate of 4.3%
during  the  first  quarter  of  1999,  yet  inflation  remained benign. Despite
concerns  that faster growth might rekindle long-dormant inflationary pressures,
the Federal Reserve Board (the "Fed") held steady on rates.

In  May,  however,  a surprisingly large jump in the Consumer Price Index pushed
policymakers  to adopt a bias towards tightening monetary policy, which caused a
shift in market psychology. As a result, market participants began to anticipate
higher    rates.

In  late  June,  the  Fed  implemented  its first 25 basis point increase in the
federal funds rate. At the same time, the Fed announced that it was shifting its
bias  back  to neutral, indicating no intention of further rate increases in the
immediate  future.  As the summer progressed, strong economic growth with rising
wages  reinforced  the  Fed's inflation concerns. At its August meeting, the Fed
raised  the  federal  funds  rate by another 25 basis points, and signaled added
resolve by also raising the discount rate.



In  the  third  quarter of 1999, GDP growth accelerated to a rapid 4.8%, yet key
indicators   of   employment  costs  and  inflation  remained  relatively  low.
Nonetheless,  the  Fed implemented a third 25 basis point rate hike in November.
The  Fed  took no action at its December meeting in an apparent attempt to quiet
markets  concerned  with potential Y2K-related disruptions. In addition, the Fed
added  liquidity  to  the  banking  system  over  year-end, leading to temporary
fluctuations  of  short-term  interest  rates.  Despite  this short-lived market
volatility, few significant Y2K problems were reported when the new year began.

During  the  fourth  quarter  of  1999,  GDP  growth  continued  to  accelerate,
increasing  by  a  robust  7.3%. Concerned by this evidence that the economy was
gaining  momentum,  the  Fed  raised  interest  rates for a fourth time in early
February  and  a  fifth  time  in  March, for a total rate increase of 125 basis
points  during  the  12-month  reporting  period.  Furthermore,  while  the  Fed
maintained  an  officially  neutral bias after its March rate hike, Fed Chairman
Alan  Greenspan  has indicated that the Fed's inflation-fighting resolve remains
undiminished.

As  of March 31, statistical data such as the Chicago Purchasing Managers Report
indicated  that  U.S. economic growth remained strong. In addition, evidence has
begun  to  emerge  that  prices  are  edging  higher.  Personal  consumption has
continued  to  advance  while  the  savings  rate dropped to its lowest level on
record, indicating that consumer spending remains strong.

Accordingly,  we  currently  believe  that  fixed-income investors widely expect
further  short-term  interest-rate  increases  at  subsequent  Fed meetings. The
question  appears  to  be not whether the Fed will raise interest rates further,
but  by how much. It is currently unclear whether the Fed will implement another
25  basis  point  increase,  or  if  they  will attempt to slow the economy more
dramatically with a 50 basis point rate hike.

                                                                        The Fund

LETTER TO SHAREHOLDERS (CONTINUED)

Market Environment/Portfolio Focus

In anticipation of rising interest rates early in the 12-month reporting period,
the  fund  adopted a somewhat defensive strategy. Most significantly, we reduced
the  fund' s  average  maturity in order to increase our flexibility. We believe
that  holding  shorter maturities at this time should enhance the fund's ability
to take advantage of any additional interest-rate increases.

As  of  March  31,  2000, the fund's average maturity remained relatively short;
however,  we  are  prepared  to  extend  the fund's average maturity if and when
evidence  appears  that the economy is slowing in response to the Fed's previous
moves.  In  the event that we look to extend the fund's average maturity when we
believe  that  the  Fed  is near the end of the current series of rate hikes, we
would  seek  to  take  advantage  of the then current interest-rate environment

    Sincerely,

NOTES TO FINANCIAL STATEMENTS

NOTE 1--Significant Accounting Policies:

Dreyfus  Institutional  Preferred  Money  Market Fund (the "fund") is registered
under  the  Investment  Company  Act  of  1940,  as  amended  (the  "Act"), as a
diversified  open-end  management  investment  company.  The  fund's investment
objective  is  to provide investors with as high a level of current income as is
consistent  with  the  preservation of capital and the maintenance of liquidity.
The Dreyfus Corporation (the "Manager") serves as the fund's investment adviser.
The  Manager is a direct subsidiary of Mellon Bank, N.A, which is a wholly-owned
subsidiary  of  Mellon  Financial Corporation. Effective March 22, 2000, Dreyfus
Service  Corporation  (" DSC"), a wholly-owned subsidiary of the Manager, became
the  distributor  of  the fund's shares. Prior to March 22, 2000, Premier Mutual
Fund Services, Inc. was the distributor.

It  is  the  fund's policy to maintain a continuous net asset value per share of
$1.00; the fund has adopted certain investment, portfolio valuation and dividend
and distribution policies to enable it to do so. There is no assurance, however,
that  the  fund  will  be able to maintain a stable net asset value per share of
$1.00.

The  fund' s  financial  statements  are  prepared  in accordance with generally
accepted accounting principles which may require the use of management estimates
and assumptions. Actual results could differ from those estimates.

(a) Portfolio valuation: Investments in securities are valued at amortized cost,
which  has been determined by the fund's Board of Trustees to represent the fair
value of the fund's investments.

(b)  Securities  transactions and investment income: Securities transactions are
recorded  on  a  trade  date  basis.  Realized  gain  and  loss  from securities
transactions  are  recorded  on  the  identified  cost basis. Interest income is
recognized  on the accrual basis. Cost of investments represents amortized cost.
Under the terms of the custody agreement, the fund receives net earnings credits
based on available cash balances left on deposit.

                                                                       The Fund

(c) Dividends to shareholders: It is the policy of the fund to declare dividends
daily  from  investment  income-net.  Such dividends are paid monthly. Dividends
from  net realized capital gain are normally declared and paid annually, but the
fund  may  make  distributions  on  a  more  frequent  basis  to comply with the
distribution  requirements of the Internal Revenue Code of 1986, as amended (the
"Code"). To the extent that a net realized capital gain can be offset by capital
loss carryovers, it is the policy of the fund not to distribute such gain.

(d) Federal income taxes: It is the policy of the fund to continue to qualify as
a  regulated  investment company, if such qualification is in the best interests
of  its  shareholders,  by complying with the applicable provisions of the Code,
and  to  make  distributions  of  taxable  income  sufficient to relieve it from
substantially all Federal income and excise taxes.

The fund has an unused capital loss carryover of approximately $17,000 available
for  Federal  income  tax  purposes  to be applied against future net securities
profits,  if  any,  realized  subsequent  to March 31, 2000. If not applied, the
carryover expires in fiscal 2008.

At  March  31, 2000, the cost of investments for Federal income tax purposes was
substantially  the  same  as  the cost for financial reporting purposes (see the
Statement of Investments).

NOTE 2--Management Fee and Other Transactions With Affiliates:

(a)  Pursuant  to a management agreement with the Manager, the management fee is
computed  at  the  annual  rate  of .10 of 1% of the value of the fund's average
daily  net  assets  and is payable monthly. The Manager has agreed to pay all of
the fund's expenses except the management fee.

The Manager compensates Dreyfus Transfer, Inc., a wholly-owned subsidiary of the
Manager,   under  a  transfer  agency  agreement  for  providing  personnel  and
facilities to perform transfer agency services for the fund.

(b)  Each trustee receives an annual fee of $1,000 and an attendance fee of $250
per  meeting.  The  Chairman  of  the  Board  receives an additional 25% of such
compensation.


REPORT OF INDEPENDENT AUDITORS

Shareholders and Board of Trustees Dreyfus Institutional Preferred Money Market
Fund

We  have audited the accompanying statement of assets and liabilities of Dreyfus
Institutional   Preferred   Money   Market  Fund,  including  the  statement  of
investments,  as  of March 31, 2000, and the related statement of operations for
the  year then ended, the statement of changes in net assets for each of the two
years  in  the period then ended, and financial highlights for each of the years
indicated  therein.  These financial statements and financial highlights are the
responsibility  of  the  Fund' 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 auditing standards generally accepted
in the 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.  An audit includes
examining,  on  a test basis, evidence supporting the amounts and disclosures in
the  financial  statements  and  financial  highlights.  Our procedures included
confirmation of securities owned as of March 31, 2000 by correspondence with the
custodian and others. An audit also includes assessing the accounting principles
used  and  significant  estimates  made by management, as well as evaluating the
overall  financial  statement presentation. 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
Dreyfus Institutional Preferred Money Market Fund at March 31, 2000, 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 indicated years, in conformity with accounting principles generally
accepted in the United States.
