Rabbi Yochanan Sofer (b. 1920s) is the Rebbe of the Erlau Hasidic dynasty, a small-sized movement in Orthodox Judaism. He was born in Erlau (nowadays Eger), Hungary, where his father and grandfather served as Grand Rabbis. After surviving the Holocaust, he continued their legacy by founding a yeshiva and a movement in their name, first in Hungary and then in Jerusalem, Israel.
