Registration Statement on Form N-1A

Ladies and Gentlemen:

On behalf of The Alger Funds (the “Trust”), transmitted for filing pursuant to Rule 485(a)(1) under the Securities Act of 1933, as amended (the “Securities Act”), is Post-Effective Amendment No. 100 (the “Amendment”) under the Securities Act to the Trust’s Registration Statement on Form N-1A (the “Registration Statement”).

The Amendment is being filed to establish the Alger 25 Fund with Class P shares.

The Trust intends to file a subsequent amendment to the Registration Statement pursuant to Rule 485(b) under the Securities Act prior to the effective date of the Amendment in order to file the consent of the Trust’s independent registered public accounting firm, to reflect the Staff comments that Fred Alger Management, Inc. has recently received, and to make certain other revisions.

Should members of the Staff have any questions or comments regarding the Amendment, please call me at 212.806.8806 or cullman@alger.com

Very truly yours,

/s/ Christopher Ullman, Esq.
