DREYFUS FLORIDA MUNICIPAL MONEY MARKET FUND
- ------------------------------------------------------------------------
LETTER TO SHAREHOLDERS

Dear Shareholder:

   We are pleased to report the performance of the Dreyfus Florida
Municipal Money Market Fund for the six months ended December 31, 1997.
Your Fund produced an annualized yield of 3.13%, and after taking into
account the effect of compounding, the annualized effective yield was
3.17%.* All dividends earned were exempt from Federal income tax and the
State of Florida intangibles taxes, although some income may be subject
to the Federal Alternative Minimum Tax (AMT) for certain shareholders.

ECONOMIC REVIEW

   Despite some fallout from Asia's financial woes, the U.S. economy
continued to display considerable strength during the recent reporting
period. Real Gross Domestic Product (GDP) growth remained steady at 3.3%
for the second and third quarters of 1997, while year-end data indicated
continuing economic strength. In November, the Commerce Department
reported a 0.8% gain in personal income, the biggest gain since June
1996 and the thirteenth consecutive monthly increase. Disposable (after-
tax) income also increased in November at a rate of 0.7%. November
produced very strong employment data, with a leap in payrolls, a dip in
the jobless rate, and another surge in hourly earnings. Consumer
confidence was on the rise in November, too, and in December it soared
to 134.5 -- its highest point in nearly three decades. Asia's financial
turmoil seemed to have left its mark, however, with some slowdown in
recent orders for big-ticket durables and a drop in November's National
Association of Purchasing Managers factory index.

   Strong economic and employment data has yet to generate a rise in
inflation, however, which has remained exceedingly low for many months.
The Labor Department reported a meager 0.1% increase in the Consumer
Price Index (CPI) for November. In fact, the annualized CPI is up just
1.8%, the smallest increase for a 12-month period in more than ten
years. Reassured by these and other reports of low and even falling
inflation, the Federal Reserve Board's Open Market Committee (FOMC)
again made no change in the Federal Funds target rate at its December
meeting. With Fed policy unchanged, short-term rates have remained in a
trading range throughout most of the period.

MARKET ENVIRONMENT/PORTFOLIO OVERVIEW

   While the Federal Reserve remained quiet over the summer months,
market technicals (i.e. supply/demand) played a major role in the short-
term municipal market. Supply of one-year notes dissipated as many
securities matured in late June and early July. This increase in
investable cash marketwide placed temporary downward pressure on yields.
In the weeks to follow, issuers returned to the market with their summer
financings, alleviating the supply and demand imbalance. While much of
that new supply was comprised of national and California-exempt
issuances, there were several attractive buying opportunities for your
Florida Fund. In early fall, increased supply of six-month and one-year
Florida-exempt notes enabled us to extend your Fund's average maturity
at attractive rates.

   As year-end approached, we saw a temporary rise in short-term rates
as a result of corporate seasonal "window dressing." In addition,
dealers priced securities at attractive levels in order to minimize
their year-end inventory. The overall decrease in demand for securities
that resulted caused yields to rise temporarily. However, assets flowed
back into the tax-exempt money funds in early January, thereby putting
downward pressure on short-term rates. During this same time period the
Florida market experienced the opposite effect. Seasonal factors caused
an inflow of assets into many Florida money market funds near year-end
and a subsequent outflow in early January. This technical situation
allowed the Florida Municipal Money Market Fund to invest while rates
were attractive in late December and then to liquidate securities into
the lower yielding environment that existed in early January. By mid-
January, the market tends to stabilize for both national and Florida-
exempt funds and normal trading patterns return. In the months ahead we
will take advantage of any additional buying opportunities as we monitor
potential Fed activity and any other significant changes in

the municipal money market. All new investments will continue to meet
the high credit quality standards which we require, and to provide a
significant level of liquidity, commensurate with the needs of your
Fund.

   Included in this report is a series of detailed statements about your Fund's
holding and its financial condition. We hope you find them informative. Please
know that we appreciate greatly your confidence in the Fund and in The Dreyfus
Corporation.

                       Very truly yours,
                       /s/ Richard J. Moynihan

  reinvested monthly.

DREYFUS FLORIDA MUNICIPAL MONEY MARKET FUND
- ------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

NOTE 1--SIGNIFICANT ACCOUNTING POLICIES:

   Dreyfus Florida Municipal Money Market Fund (the "Fund") is
registered under the Investment Company Act of 1940 ("Act") as a non-
diversified open-end management investment company. The Fund's
investment objective is to provide investors with as high a level of
current income exempt from Federal income tax as is consistent with the
preservation of capital and the maintenance of liquidity. The Dreyfus
Corporation ("Manager") serves as the Fund's investment adviser. The
Manager is a direct subsidiary of Mellon Bank, N.A. Premier Mutual Fund
Services, Inc. is the distributor of the Fund's shares, which are sold
to the public without a sales charge.

   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. Interest income,
adjusted for amortization of premiums and original issue discounts on
investments, is earned from settlement date and recognized on the
accrual basis. Realized gain and loss from securities transactions are
recorded on the identified cost basis. Cost of investments represents
amortized cost.

   The Fund follows an investment policy of investing primarily in
municipal obligations of one state. Economic changes affecting the state
and certain of its public bodies and municipalities may affect the
ability of issuers within the state to pay interest on, or repay
principal of, municipal obligations held by 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, if any, 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. To the extent that 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, which can distribute tax
exempt dividends, by complying with the applicable provisions available
of the Internal Revenue Code, and to make distributions of income and
net realized capital gain sufficient to relieve it from substantially
all Federal income and excise taxes.

   The Fund has an unused capital loss carryover of approximately
$29,000 available for Federal income tax purposes to be applied against
future net securities profits, if any, realized subsequent to June 30,
1997. If not applied, $3,000 of the carryover expires in fiscal 2003,
$23,000 expires in fiscal 2004 and $3,000 expires in fiscal 2005.

   At December 31, 1997, 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).
