Report of Independent Registered Public Accounting Firm

To the Board of Trustees
Dreyfus New York AMT-Free Municipal Money Market Fund

We have examined management's assertion, included
in the accompanying Management Statement Regarding
Compliance with Certain Provisions of the Investment
Company Act of 1940 that
Dreyfus New York AMT-Free Municipal Money Market Fund
(the "Company") complied with the requirements of
subsections (b) and (c) of Rule 17f-2 under the Investment
Company Act of 1940 ("the Act") as of July 31, 2013.

Management is responsible for the Company's compliance with those requirements. Our responsibility is to express an opinion on management's assertion about the Company's compliance based on our examination.

Our examination was conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States) and, accordingly, included examining, on a test basis, evidence about the Company's compliance with those requirements and performing such other procedures as we considered necessary in the circumstances. Included among our procedures were the following tests performed as of July 31, 2013, and with respect to agreement of security and similar investment purchases and sales, for the period from June 30, 2013 (the date of our last examination) through July 31, 2013:

Count and inspection of all securities and similar investments located in the vault of The Bank of New York Mellon in New York and London, if any, without prior notice to management;

Confirmation of all securities and similar investments held by institutions in book entry form (i.e., the Federal Reserve Bank of Boston, the Depository Trust Company and various sub-custodians);

Reconciliation of all such securities and similar investments to the books and records of the Company and The Bank of New York Mellon;

Confirmation of all securities hypothecated, pledged, placed in escrow, or out for transfer with brokers, pledgees, transfer agents or securities lending administrators;

Confirmation of all repurchase agreements, if any, with brokers/banks or to documentation of corresponding subsequent cash receipts and agreement of underlying collateral with The Bank of New York Mellon's records;

Agreement of pending purchase activity as of July 31, 2013 to documentation of subsequent broker statements;

Agreement of Dreyfus Family of Funds' (the "Funds") trade tickets for 5 security purchases and 5 security sales or maturities for the period from July 1, 2013 through July 31, 2013, to the books and records of the Funds noting that they had been accurately recorded and subsequently settled;

We believe that our examination provides a reasonable basis for our opinion. Our examination does not provide a legal determination on the Company's compliance with specified requirements.

In our opinion, management's assertion that Dreyfus New York AMT-Free Municipal Money Market Fund complied with the requirements of subsections (b) and (c) of Rule 17f-2 of the Act as of July 31, 2013 with respect to securities and similar
investments reflected in the investment account of the Company is fairly stated, in all material respects.

This report is intended solely for the information and use of management and the Board of Trustees of
Dreyfus New York AMT-Free Municipal Money Market Fund and the Securities and Exchange Commission and is not intended to be and should not be
used by anyone other than these specified parties.
