Avraham Haim Yosef (Avi) haCohen Weiss (Hebrew: אברהם חיים יוסף הכהן ווייס; born June 24, 1944) is an American Open Orthodox ordained rabbi, author, teacher, lecturer, and activist who led the Hebrew Institute of Riverdale in The Bronx, New York until 2015. He is the founder of Yeshivat Chovevei Torah for men and Yeshivat Maharat for women, rabbinical seminaries that are tied to Open Orthodoxy, a breakaway movement that Weiss originated, which is to the left of Modern Orthodox Judaism and to the right of Conservative Judaism. He is co-founder of the International Rabbinic Fellowship, a rabbinical association that is a liberal alternative to the Orthodox Rabbinical Council of America, and founder of the grassroots organization Coalition for Jewish Concerns – Amcha.
Semikhah (rabbinical ordination) of women by Weiss' movement has been a source of friction within Orthodox Judaism.
