Sefer Hamitzvot ("Book of Commandments", Hebrew: ספר המצוות; Judeo-Arabic: כתאב אלפראיץׄ) is a work by the 12th-century rabbi, philosopher, and physician, Moses Maimonides.

A new Hebrew translation from the original Judaeo-Arabic was made by the noted Yemenite scholar, Rabbi Yosef Qafih.

[1] In the work, Maimonides lists all the 613 mitzvot traditionally contained in the Torah (Pentateuch).

The work is the subject of a number of commentaries, including one from Nahmanides, one titled Megillath Esther ("Scroll of Esther", by Isaac Leon ibn Zur (although often incorrectly attributed to Isaac de Leon), bearing no direct relationship with the Biblical Book of Esther), and others titled Lev Sameach (by Rabbi Abraham Allegri) and Kinath Soferim.

After their promotion by the late Rabbi Menachem Mendel Schneerson, several of Maimonides's works are studied daily by followers of the Chabad movement.
