Rav Eliezer Yehuda Finkel (also called Leizer Yudel Finkel) is a Haredi Jewish rosh yeshiva (dean) of the Mir Yeshiva in Jerusalem, which is considered to be the largest yeshiva in Israel with a student body of 9,500 students.
He acceded to the position of rosh yeshiva after his father, Rabbi Nosson Tzvi Finkel, died suddenly on 8 November 2011.
Finkel was named after his maternal great-grandfather, Rabbi Eliezer Yehuda Finkel, who became rosh yeshiva (dean) of the Mir yeshiva in Poland in 1917 and re-established the yeshiva in Jerusalem during World War II while the main body of the yeshiva was in exile in the Far East. His great-great-grandfather was the Mussar movement leader Nosson Tzvi Finkel.
