BARUCH BEN ISAAC OF REGENSBURG (second half of 12th century), talmudic scholar. He was a member of the bet din of Regensburg, together with *Isaac b. Jacob Ha-Lavan of Prague, Abraham ben Moses of Regensburg, and *Judah he-Ḥasid b. Samuel (Sefer Ḥasidim, ed. by J. Wistinetzki (19242), 390). Baruch was one of the teachers of *Abraham b. Azriel, the author of Arugat ha-Bosem. There is record of a question addressed to Baruch and his two fellow judges by R. *Joel ben Isaac ha-Levi (Sefer Ravyah, no. 1031). Baruch engaged in disputations with his older contemporary *Eliezer b. Nathan of Mainz, who esteemed him highly, and with *Isaac b. Samuel ha-Zaken of Dampierre. Some scholars have incorrectly identified him with *Baruch b. Isaac of Worms, author of the Sefer ha-Terumah.
