Avraham Osdoba is an Orthodox rabbi and a member of the Chabad Hasidic movement.

Rabbi Osdoba serves as a rosh yeshiva in 770 in addition to being a member of the Bais Din Tzedek (Jewish Rabbinical Court) of the Chabad community in Crown Heights, Brooklyn; he is an authority on Halacha (Jewish law), Talmud and Hasidic philosophy.

In 1986, the Lubavitcher Rebbe encouraged the chasidim to vote for the members of the bais din.
