Chaim Yehuda Leib Auerbach (1883 – 26 September 1954) was a Haredi rabbi and roshei yeshiva of Shaar Hashamayim Yeshiva, a landmark Jerusalem institution specializing in Talmudic and kabbalah studies for Ashkenazi scholars that he helped found in 1906. The yeshiva still exists today. Known for his great love and personal sacrifice for Torah and Torah scholars, Auerbach raised sons who also became great scholars — including his eldest son, Rabbi Shlomo Zalman Auerbach, a preeminent posek of the mid- to late-twentieth century.
