LETTER FROM THE CHAIRMAN

  Dear Shareholder:

We are pleased to present this semiannual report for Dreyfus New Jersey Municipal Money Market Fund, Inc., covering the six-month period from December 1, 2005, through May 31, 2006.

Since June 2004, the Federal Reserve Board (the “Fed”) has attempted to manage U.S. economic growth and forestall potential inflation by gradually raising short-term interest rates. In our view, the Fed’s shift from a stimulative monetary policy to a neutral one has so far been successful: the economy has grown at a moderate pace, the unemployment rate has dropped, corporate profits have risen, and inflation has generally remained in check despite recent cost pressures stemming from higher energy and import prices.

As we near the second half of the year, the financial markets appear more likely to be influenced not by what the Fed already has accomplished, but by investors’ expectations of what is to come, including the Fed’s decision to increase rates further, maintain them at current levels or reduce them to stimulate future growth. We believe that this decision will depend largely on the outlook for core inflation in 2007.The Fed probably can stand pat as long as it expects inflation to remain subdued. But if inflationary pressures continue to build, the Fed may choose to tighten monetary policy further.

For information about how the fund performed during the reporting period, as well as market perspectives, we have provided a Discussion of Fund Performance given by the fund’s portfolio manager.

Thank you for your continued confidence and support.

DISCUSSION OF FUND PERFORMANCE

Joseph Irace, Portfolio Manager

How did Dreyfus New Jersey Municipal Money Market Fund perform during the period?

For the six-month period ended May 31, 2006, the fund produced an annualized yield of 2.53% . Taking into account the effects of compounding, the fund produced an annualized effective yield of 2.56% .1

We attribute the fund’s results to rising short-term interest rates in a recovering economy as well as supply-and-demand factors affecting tax-exempt money market instruments.

What is the fund’s investment approach?

The fund’s objective is to seek as high a level of current income exempt from federal and New Jersey state income taxes as is consistent with the preservation of capital and the maintenance of liquidity.The fund also seeks to maintain a stable $1.00 share price. To pursue its goal, the fund normally invests substantially all of its assets in short-term, high-quality municipal obligations that provide income exempt from federal and New Jersey state income taxes.

When pursuing the fund’s objective, we employ two primary strategies. First, we attempt to add value by constructing a portfolio of high-quality, tax-exempt money market municipal obligations that provide income exempt from federal and New Jersey state income taxes. Second, we actively manage the fund’s average maturity in anticipation of interest-rate trends and supply-and-demand changes in New Jersey’s short-term municipal marketplace.

For example, if we expect an increase in short-term supply, we may reduce the weighted average maturity of the fund, which should better position the fund to purchase new securities with higher yields, if higher yields materialize.Yields tend to rise when there is an increase in new-issue supply competing for investor interest. New

The Fund 3


DISCUSSION OF FUND PERFORMANCE (continued)

securities generally are issued with maturities in the one-year range and tend to lengthen the fund’s weighted average maturity if purchased. If we anticipate limited new-issue supply, we may extend the fund’s average maturity to maintain then-current yields for as long as we think practical. At other times, we try to maintain an average maturity that reflects our view of short-term interest-rate trends and future supply-and-demand considerations.

What other factors influenced the fund’s performance?

While inflation appeared to be subdued at the end of 2005, inflation-related concerns intensified over the first five months of 2006 as the U.S. economic expansion gained momentum and energy prices surged to record highs. In its ongoing attempts to forestall an acceleration of inflation, the Federal Reserve Board (the “Fed”) raised short-term interest rates four times, driving the overnight federal funds rate to 5% by the reporting period’s end.

Yields of tax-exempt money market instruments generally rose along with interest rates, reaching their highest levels in five years. However, yields of shorter-dated money market securities climbed more sharply than longer-dated securities, causing yield differences along the tax-exempt money market yield spectrum to narrow toward historical lows. By the end of the reporting period there was little difference in the yields of tax-exempt securities with maturities between six months and four years. Investors therefore continued to focus primarily on instruments maturing in six months or less. Even institutional investors who normally favor longer-term securities began to purchase tax-exempt money market securities, adding to demand and putting downward pressure on yields.

Due to low yields from very short-term, floating-rate instruments, we tended to focus on tax-exempt commercial paper and seasoned municipal notes and bonds maturing over six to nine months. We occasionally found opportunities among instruments with somewhat longer maturities, enabling us to construct a “laddered” portfolio of

4

securities scheduled to mature at different times. This strategy is designed to help protect the fund’s yield while ensuring that cash remains available for redemptions and new investments.

Finally, New Jersey’s fiscal condition continued to benefit from the recovering economy, including better conditions on Wall Street, where many of the state’s residents work. However, a number of fiscal challenges face Governor Corzine in his first year in office, including the need to replenish the state’s Transportation Trust Fund to pay for needed highway, bridge and mass transit projects.

What is the fund’s current strategy?

While recent data suggested that the U.S. economy remains on a path of sustainable growth, the economy and the Fed have sent mixed messages with regard to inflation and the possibility that the rate of economic expansion may begin to slow. As a result, while it currently appears that at least one or two additional rate hikes are likely, we believe that short-term interest rates are unlikely to rise substantially above current levels, especially if high energy prices curtail consumer spending. In addition, with the expected increase in issuance during the traditional summertime “note season,” our current laddered investment approach should help the portfolio capture incrementally higher yields if they become available. Should we become convinced that interest rates have peaked, we are prepared to extend the fund’s weighted average maturity in an attempt to lock in high current yields.

COMPARING YOUR FUND’S EXPENSES WITH THOSE OF OTHER FUNDS (Unaudited)

Using the SEC’s method to compare expenses

The Securities and Exchange Commission (SEC) has established guidelines to help investors assess fund expenses. Per these guidelines, the table below shows your fund’s expenses based on a $1,000 investment, assuming a hypothetical 5% annualized return. You can use this information to compare the ongoing expenses (but not transaction expenses or total cost) of investing in the fund with those of other funds.All mutual fund shareholder reports will provide this information to help you make this comparison. Please note that you cannot use this information to estimate your actual ending account balance and expenses paid during the period.

Expenses and Value of a $1,000 Investment assuming a hypothetical 5% annualized return for the six months ended May 31, 2006

Expenses paid per $1,000     $ 3.23 
Ending value (after expenses)    $1,021.74 

Expenses are equal to the fund’s annualized expense ratio of .64%, multiplied by the average account value over the 
period, multiplied by 182/365 (to reflect the one-half year period).

NOTES TO FINANCIAL STATEMENTS (Unaudited)

NOTE 1—Significant Accounting Policies:

Dreyfus New Jersey Municipal Money Market Fund, Inc. (the “fund”) is registered under the Investment Company Act of 1940, as amended (the “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 and New Jersey state income taxes as is consistent with the preservation of capital and the maintenance of liquidity.The Dreyfus Corporation (the “Manager” or “Dreyfus”) serves as the fund’s investment adviser.The Manager is a wholly-owned subsidiary of Mellon Financial Corporation (“Mellon Financial”). Dreyfus Service Corporation (the “Distributor”), a wholly-owned subsidiary of the Manager, 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 U.S. generally accepted accounting principles, which may require the use of management estimates and assumptions. Actual results could differ from those estimates.

The fund enters into contracts that contain a variety of indemnifications. The fund’s maximum exposure under these arrangements is unknown.The fund does not anticipate recognizing any loss related to these arrangements.

(a) Portfolio valuation: Investments in securities are valued at amortized cost in accordance with Rule 2a-7 of the Act, which has been determined by the Board of Directors to represent the fair value of the fund’s investments.

The Fund 21


NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

(b) Securities transactions and investment income: Securities transactions are recorded on a trade date basis. Interest income, adjusted for accretion of discount and amortization of premium 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 has an arrangement with the custodian bank whereby the fund receives earnings credits from the custodian when positive cash balances are maintained, which are used to offset custody fees. For financial reporting purposes, the fund includes net earnings credits, if any, as an expense offset in the Statement of Operations.

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 of 1986, as amended (the “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 of the Code, and to make distributions of income and net realized capital gain sufficient to relieve it from substantially all federal income and excise taxes.

22

The fund has an unused capital loss carryover of $162 available for federal income tax purposes to be applied against future net securities profits, if any, realized subsequent to November 30, 2005. If not applied, the carryover expires in fiscal 2006.

The tax character of distributions paid to shareholders during the fiscal periods ended November 30, 2005 and January 31, 2005 were all tax exempt income.The tax character of current year distributions will be determined at the end of the current fiscal year.

At May 31,2006,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 .50% of the value of the fund’s average daily net assets and is payable monthly.

(b) Under the Shareholder Services Plan, the fund reimburses the Distributor, an amount not to exceed an annual rate of .25% of the value of the fund’s average daily net assets for certain allocated expenses of providing personal services and/or maintaining shareholder accounts.The services provided may include personal services relating to shareholder accounts, such as answering shareholder inquiries regarding the fund and providing reports and other information, and services related to the maintenance of shareholder accounts. During the period ended May 31, 2006, the fund was charged $97,409 pursuant to the Shareholder Services Plan.

The fund 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.

The Fund 23


NOTES TO FINANCIAL STATEMENTS (Unaudited) (continued)

During the period ended May 31, 2006, the fund was charged $46,241 pursuant to the transfer agency agreement.

During the period ended May 31, 2006, the fund was charged $1,926 for services performed by the Chief Compliance Officer.

The components of Due to The Dreyfus Corporation and affiliates in the Statement of Assets and Liabilities consist of: management fees $155,033, chief compliance officer fees $1,605 and transfer agency per account fees $15,600.

(c) Each Board member also serves as a Board member of other funds within the Dreyfus complex. Annual retainer fees and attendance fees are allocated to each fund based on net assets.

INFORMATION ABOUT THE REVIEW AND APPROVAL OF THE FUND’S MANAGEMENT AGREEMENT (Unaudited)

At a meeting of the fund’s Board of Directors held on April 18, 2006, the Board considered the re-approval for an annual period of the fund’s Management Agreement, pursuant to which the Manager provides the fund with investment advisory and administrative services. The Board members, none of whom are “interested persons” (as defined in the Investment Company Act of 1940, as amended) of the fund, were assisted in their review by independent legal counsel and met with counsel in executive session separate from representatives of the Manager.

Analysis of Nature, Extent, and Quality of Services Provided to the Fund. The Board members received a presentation from representatives of the Manager regarding services provided to the fund and other funds in the Dreyfus fund complex, and discussed the nature, extent, and quality of the services provided to the fund pursuant to its Management Agreement.The Manager’s representatives reviewed the fund’s distribution of accounts and the relationships the Manager has with various intermediaries and the different needs of each. The Manager’s representatives noted the diversity of distribution of the fund as well as among the funds in the Dreyfus fund complex, and the Manager’s corresponding need for broad, deep, and diverse resources to be able to provide ongoing shareholder services to each of the fund’s distribution channels. The Board also reviewed the number of shareholder accounts in the fund, as well as the fund’s asset size.

The Board members also considered the Manager’s research and portfolio management capabilities. The Board members also considered that the Manager also provides oversight of day-to-day fund operations, including fund accounting and administration and assistance in meeting legal and regulatory requirements, and the Manager’s extensive administrative, accounting and compliance infrastructure.

Comparative Analysis of the Fund’s Management Fee, Expense Ratio, and Performance. The Board members reviewed reports prepared by Lipper, Inc., an independent provider of investment company data, which included information comparing the fund’s management fee and expense ratio with a group of comparable funds (the “Expense

The Fund 25

Group”) and with a broader group of funds (the “Expense Universe”) that were selected by Lipper. Included in these reports were comparisons of contractual and actual management fee rates, total operating expenses, and total return performance.The Manager furnished these reports to the Board along with a description of the methodology Lipper used to select the Expense Group and Expense Universe.

The Board reviewed the results of the Expense Group and Expense Universe comparisons for various periods ended February 28, 2006. The Board reviewed the range of management fees and expense ratios of the funds in the Expense Group and Expense Universe, and noted that the fund’s contractual and actual management fees were at and above the Expense Group medians, respectively.The Board also noted that the fund’s total expense ratio was lower than the Expense Group and Expense Universe medians.

The Board members also reviewed the reports prepared by Lipper that presented the fund’s performance for various periods ended February 28, 2006, and placed significant emphasis on comparisons of total return performance among the same group of funds as the Expense Group (the “Performance Group”) and to a group of funds that was broader than the Expense Universe (the “Performance Universe”) that also was selected by Lipper.The Board noted that the fund’s total returns were generally at or near the Performance Group and Performance Universe medians for most of the reported time periods up to 10 years.

Representatives of the Manager reviewed with the Board members the fee paid to the Manager or its affiliates by the one mutual fund managed by the Manager or its affiliates reported in the same Lipper category as the fund (the “Similar Fund”), and explained the nature of the Similar Fund and any differences, from the Manager’s perspective, in providing services to the Similar Fund as compared to the fund. The Manager’s representatives also reviewed the costs associated with distribution through intermediaries. The Board discussed the relationship of the management fees paid in light of the Manager’s performance, and the services provided.The Board members considered the relevance of the

fee information provided for the Similar Fund, to evaluate the appropriateness and reasonableness of the fund’s management fee.The Board noted that the Similar Fund paid the same contractual management fee rate as the fund.

Representatives of the Manager noted that there were no similarly managed institutional separate accounts or wrap fee accounts managed by the Manager or its affiliates with similar investment objectives, policies, and strategies as the fund.

Analysis of Profitability and Economies of Scale. The Manager’s representatives reviewed the dollar amount of expenses allocated and profit received by the Manager and the method used to determine such expenses and profit. The Board considered information, previously provided and discussed, prepared by an independent consulting firm regarding the Manager’s approach to allocating costs to, and determining the profitability of, individual funds and the entire Dreyfus mutual fund complex. The Board members also considered that the methodology had also been reviewed by an independent registered public accounting firm which, like the consultant, found the methodology to be reasonable. The consulting firm also analyzed where any economies of scale might emerge in connection with the management of the fund. The Board members evaluated the profitability analysis in light of the relevant circumstances for the fund, including the extent to which economies of scale would be realized if the fund grows and whether fee levels reflect these economies of scale for the benefit of fund shareholders.The Board members also considered potential benefits to the Manager from acting as investment adviser to the fund and noted that there were no soft dollar arrangements in effect with respect to trading the fund’s portfolio.

It was noted that the Board members should consider the Manager’s profitability with respect to the fund as part of their evaluation of whether the fees under the Management Agreement bear a reasonable relationship to the mix of services provided by the Manager, including the nature, extent, and quality of such services. It was noted that the

The Fund 27

profitability percentage for managing the fund was within ranges determined by appropriate court cases to be reasonable given the services rendered and that the profitability percentage for managing the fund was reasonable given the fund’s overall performance and generally superior service levels provided.

At the conclusion of these discussions, the Board agreed that it had been furnished with sufficient information to make an informed business decision with respect to continuation of the fund’s Management Agreement. Based on the discussions and considerations as described above, the Board made the following conclusions and determinations.

  • The Board concluded that the nature, extent, and quality of the ser- vices provided by the Manager are adequate and appropriate.
  • The Board was satisfied with the fund’s performance.
  • The Board concluded that the fee paid to the Manager by the fund was reasonable in light of the services provided, comparative perfor- mance and expense and advisory fee information, costs of the services provided, and profits to be realized and benefits derived or to be derived by the Manager from its relationship with the fund.
  • The Board determined that the economies of scale which may accrue to the Manager and its affiliates in connection with the man- agement of the fund had been adequately considered by the Manager in connection with the management fee rate charged to the fund, and that, to the extent in the future it were to be deter- mined that material economies of scale had not been shared with the fund, the Board would seek to have those economies of scale shared with the fund.

The Board members considered these conclusions and determinations, along with the information received on a routine and regular basis throughout the year, and, without any one factor being dispositive, the Board determined that re-approval of the fund’s Management Agreement was in the best interests of the fund and its shareholders.
