EXHIBIT 99.1


                                             March 18, 1998





Dear Participant:

As of March 4, 1998, the trust ("RRP Trust") established for the
Columbia Federal Savings Bank (the "Bank") Recognition and
Retention Plan for Officers and Employees ("RRP") held 22,644
shares of common stock of Haven Bancorp, Inc. (the "Company"), the
parent holding company for the Bank.  As a participant in the RRP,
you may direct the voting of the shares of the Company's common
stock held by the RRP Trust that have been granted to you under the
RRP.

An unrelated corporate trustee for the RRP has been appointed,
ChaseMellon Shareholder Services L.L.C. (the "RRP Trustee").  We,
the Board of Directors, are forwarding to you the attached Vote
Authorization Form, provided for the purpose of conveying your
voting instructions to the RRP Trustee.  The RRP Trustee will vote
those shares of the Company's common stock held in the RRP Trust
that have been granted to participants in accordance with
instructions received from the participants.  If the RRP Trustee
does not receive voting instructions with respect to shares that
have been granted to participants, the RRP Trustee will vote such
shares in the same proportion as those shares which have been
awarded and voted.  

At this time, in order to direct the voting of shares granted to
you under the RRP, you must fill out and sign the enclosed Vote
Authorization Form and return it in the accompanying envelope. 
Your vote will not be revealed, directly or indirectly, to any
director, officer or other employee of the Company or the Bank. 
Your shares will be tallied by an independent source and then the
RRP Trustee will vote the shares in the RRP Trust based on the
voting instructions it has received from participants, as described
above.

                                        Sincerely,




                                        The Board of Directors






                    HAVEN BANCORP, INC.
