Yochanan Sofer (January 1, 1923 – February 22, 2016) was the Rebbe of the Erlau dynasty,which though not the largest in the number of its adherents is still a significant movement within Haredi Judaism.
He was born in Eger (German: Erlau), 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 a few years later in Jerusalem, Israel.
