Meshullam Feivush Heller of Zbarazh (ca. 1742– 12 December 1794) was the author of several Hasidic sefarim. Rabbi Meshullam Feivush was born to a rabbinic family. His father was a direct descendant of Rabbi Yom-Tov Lipmann Heller and his mother was a descendant of Rabbi Judah ben Samuel of Regensburg. Rabbi Meshullam Feivush was also a descendant of Rabbis Samson ben Pesah Ostropoli and Solomon Luria. Rabbi Meshullam Feivush spent most of his life in Zbarazh. He did not serve in any official position. He was primarily a disciple of the Maggid of Zlotshov although he also basked in the presence of the Maggid of Mezritch. His older brother, a non-Hasidic Kabbalist and the Av Beit Din of Dolyna (d. 1786), also authored a sefer with his endorsement which appears in its beginning. Rabbi Meshullam Feivush was married twice. He had one son by his first wife and two sons by his second wife. He was a close friend of Rabbi Hayyim Tyrer who cites him in his works. He died at Zbarazh, 12 December 1794 and was buried at Zbarazh.
