YEAR 2000 ISSUES (UNAUDITED)

  The  fund  could  be  adversely  affected  if the computer systems used by The
Dreyfus  Corporation  and  the  fund' s  other service providers do not properly
process  and  calculate date-related information from and after January 1, 2000.
The  Dreyfus  Corporation  is working to avoid Year 2000-related problems in its
systems  and  to  obtain  assurances  from other service providers that they are
taking  similar  steps.  In  addition,  issuers  of securities in which the fund
invests may be adversely affected by Year 2000-related problems. This could have
an impact on the value of the fund's investments and its share price.

LETTER TO SHAREHOLDERS

Dear Shareholder:

  We  are  pleased to report the performance for the Dreyfus Variable Investment
Fund  -- Money Market Portfolio for the 12-month period ended December 31, 1998.
For  the period, your Portfolio produced a yield of 5.01% and, after taking into
account the effect of compounding, the effective yield was 5.12%.*

ECONOMIC REVIEW

  During  1998,  the  main  regions  of  the  world  had very different economic
fundamentals.  The  U.S.  entered  the  year  with  a  strong  economy near full
employment, with unemployment only slightly above 4%. The tight labor market led
the  Federal  Reserve Board to contemplate a rise in interest rates early in the
year,  but  world  economic  weakness  generated powerful enough disinflationary
forces  that  the Fed acted instead to ease credit beginning in September. After
many  years of subpar economic growth, continental Europe moved into a sustained
economic  expansion. The overall European economy benefited as interest rates in
peripheral  countries such as Spain and Italy fell, approaching the lower levels
established  by  Germany,  on  the eve of currency unification. Unlike the U.S.,
Europe  has  substantial excess capacity of productive plant and labor. In Asia,
weak  economies  were  pervasive  as  a  result of a financial crisis. The Latin
American  economies weakened in turn as the financial stresses spread throughout
that  region. On balance, there was a substantial weakening of the world economy
over  the  course  of  1998  moderated mainly by the American consumer's role as
"spender of last resort."

A main influence on the U.S. economy during the year was the foreign financial
crisis  and  consequent  cooling  of the world economy. The positive effects hit
first.  Actual  inflation  and  expected inflation dropped, causing a decline in
long-term  Treasury  bond  yields  and  mortgage  rates.  This  caused a boom in
housing.  The  fall in inflation left more of the growth in consumer income with
which to buy goods and services. Thus, consumers benefited from a combination of
good  growth  in income after inflation, a strong labor market, and increases in
the  prices  of assets they owned, including bonds, stocks and real estate. In a
sense,  1998  was  a  year  of  disinflationary boom in the U.S., as above-trend
economic growth coincided with negligible inflation.

  The  negative  effect of Asian weakness was felt in the industrial sector more
than  in  the consumer sector. Corporate profits weakened, especially in sectors
affected  by  the Asian crisis such as world-traded commodities (oil, metals and
paper)    and    exports.

  Evidence  of  a  weaker world economy accumulated during 1998 as the financial
stresses  continued.  A  worsened  financial crisis occurred between the Russian
default  in  mid-August  and  the  fallout from the Long Term Capital Management
hedge  fund crisis through early October. However, energetic steps were taken to
stabilize the Japanese banks, design a support package for Brazil, ease monetary
policy,   and  help  overinvested  financial  institutions  rebuild  their  cash
reserves.  Indications of a calming of financial fears were evident in the final
months  of  the  year.  In  any  case, there appears to have been a shift in the
priorities   of   key   policymakers   from   fighting  potential  inflation  to
restimulating future world economic growth.

  The  global  economy  survived  a  triple financial crisis in 1998 from Japan,
emerging  market  countries  and  overextended  financial  institutions.  Excess
capacity  persists  in  many  worldwide  industries  after years of high capital
spending  followed by the onset of a worldwide weakening in demand. Fortunately,
the  U.S.  has led the world in making the transition from the old manufacturing
industries  to  the  new  growth  industries,  such  as biotechnology, software,
computer   hardware   and  the  Internet.  This  contributed  to  the  favorable
combination  of low unemployment and low inflation in the U.S., and may yet lead
toward more efficient allocation of capital elsewhere in the world.

  As  1998 ended, interest rates set by central banks remained in a downtrend in
most  parts  of the world including Europe and the U.S. A similar trend had even
begun in many emerging countries, as the stresses of financial crisis relaxed.

MARKET ENVIRONMENT/PORTFOLIO FOCUS

  The  economic  forces described above drove down interest rates in late summer
and  early  fall. Later in the year there was a modest increase in rates. One of
its  effects  was to change the yield curve from one that had been negative to a
positive,  sloping  structure.  In this normal configuration, longer-term yields
exceeded those of the shorter-term instruments.

  A  flight  to  safety  by  global  investors  was  the  force  that drove down
longer-term  U.S.  yields  last  fall. In recent weeks, investors appear to have
become  more  confident about the economic outlook. One factor has been the rise
in  interest rates in Japan, which brought about some repatriation of investment
funds to that country. In addition, the introduction of the Euro currency at the
start  of  the  new year, which was well received, put some downward pressure on
the U.S. dollar.

Investor fears of worldwide financial turmoil seemed to have receded recently.
Currently,  prices  and  rates in the money market appear to be reacting more to
underlying  economic  forces  than  to  such market psychology factors. This, of
course,   can   be   constructive  for  investors  in  short-term  money  market
instruments.

The fact that the Federal Reserve Open Market Committee lowered interest rates
three  times  between  late  September  and year-end seems to have been a strong
confidence-building  factor  in  the  markets.  Currently,  we expect the Fed to
remain in a "wait and see" mode for a while.

  During  the reporting period, we lengthened the average portfolio maturity, as
we  deemed appropriate in order to take advantage of possible declining interest
rates.  We  will  continue  to  monitor the market, including interest rates, in
seeking investment opportunities for the Portfolio.

               Sincerely,



               [Patricia A. Larkin signature]

DREYFUS VARIABLE INVESTMENT FUND, MONEY MARKET PORTFOLIO
- --------------------------------------------------------------------------------

NOTES    TO    FINANCIAL    STATEMENTS

NOTE 1--SIGNIFICANT ACCOUNTING POLICIES:

   Dreyfus  Variable  Investment  Fund  (the  "Fund" ) is  registered  under the
Investment Company Act of 1940, as amended (the "Act") as an open-end management
investment  company,  operating  as a series company currently offering thirteen
series,  including  the Money Market Portfolio (the "Series") and is intended to
be  a funding vehicle for variable annuity contracts and variable life insurance
policies to be offered by the separate accounts of life insurance companies. The
Series  is  a  diversified  portfolio.  The  Series'  investment objective is to
provide as high a level of current income as is consistent with the preservation
of capital and the maintenance of liquidity. The Dreyfus Corporation ("Dreyfus")
serves  as  the  Series'  investment  adviser. Dreyfus is a direct subsidiary of
Mellon  Bank,  N.A. Premier Mutual Fund Services, Inc. is the distributor of the
Series' shares, which are sold without a sales charge.

   It  is  the Series' policy to maintain a continuous net asset value per share
of  $1.00;  the  Series  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  accounts  separately for the assets, liabilities and operations of
each  series.  Expenses directly attributable to each series are charged to that
series'  operations;  expenses  which are applicable to all series are allocated
among them on a pro rata basis.

   The  Series'  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 are valued at amortized cost, which has
been  determined  by the Fund's Board of Trustees to represent the fair value of
the Series' 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 Series received net earnings
credits  of  $5,637 during the period ended December 31, 1998 based on available
cash  balances left on deposit. Income earned under this arrangement is included
in interest income.

   The  Series may enter into repurchase agreements with financial institutions,
deemed  to  be  creditworthy  by  the  Fund' s  Manager, subject to the seller's
agreement to repurchase and the Series' agreement to resell such securities at a
mutually   agreed   upon  price.  Securities  purchased  subject  to  repurchase
agreements  are  deposited with the Series' custodian and, pursuant to the terms
of the repurchase agreement, must have an aggregate market value greater than or
equal  to  the terms of the repurchase price plus accrued interest at all times.
If  the  value  of  the  underlying  securities  falls  below  the  value of the
repurchase  price  plus  accrued interest, the Series will require the seller to
deposit  additional  collateral  by  the  next  business day. If the request for
additional  collateral  is  not  met,  or  the seller defaults on its repurchase
obligation,  the  Series maintains its right to sell the underlying seurities at
market value and may claim any resulting loss against the seller.

   (D)  DIVIDENDS  TO  SHAREHOLDERS:  It  is the policy of the Series to declare
dividends  daily  from  investment  income-net. Such dividends are paid monthly.
Dividends from net realized capital gain, if any, are normally declared and paid
annually,  but  the  Series  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 Series not to
distribute such gain.

- -----------------------------------------------------------------------------

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

   (E)  FEDERAL  INCOME  TAXES:  It  is  the policy of the Series 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  Series  has  an  unused  capital  loss carryover of approximately $3,550
available  for  Federal  income  tax  purposes  to be applied against future net
securities  profits,  if  any,  realized  subsequent  to  December 31, 1998. The
carryover  does not include net realized securities losses from November 1, 1998
through December 31, 1998 which are treated, for Federal income tax purposes, as
arising  in fiscal 1999. If not applied, $850 of the carryover expires in fiscal
2004, $1,300 expires in fiscal 2005 and $1,400 expires in fiscal 2006.

NOTE 2--INVESTMENT ADVISORY FEE AND OTHER TRANSACTIONS WITH AFFILIATES:

(A) Pursuant to an Investment Advisory Agreement with Dreyfus, the investment
advisory  fee  is  computed  at the annual rate of .50 of 1% of the value of the
Series' average daily net assets and is payable monthly.

   The  Series  compensates Dreyfus Transfer, Inc., a wholly-owned subsidiary of
Dreyfus,   under  a  transfer  agency  agreement  for  providing  personnel  and
facilities to perform transfer agency services for the Series. During the period
ended  December  31,  1998,  the Series was charged $86 pursuant to the transfer
agency agreement.

   (B)  Each  trustee  who  is  not an "affiliated person" as defined in the Act
receives from the Fund an annual fee of $2,500 and an attendance fee of $250 per
meeting.  The  Chairman  of  the  Board  receives  an  additional  25%  of  such
compensation.
