Aharon Rokeach (19 December 1880 – 18 August 1957) was the fourth Rebbe of the Belz Hasidic dynasty. He led the movement from 1926 until his death in 1957. Rokeach inherited the mantle of leadership from his father, Yissachar Dov Rokeach, upon the latter's death in 1926. Known for his piety and mysticism, Rokeach was called the "Wonder Rabbi" by Jews and gentiles alike for the miracles he purportedly performed.
