Yechiel Yitzchok Perr (born 1935) is an American Haredi rabbi and the founder and rosh yeshiva of Yeshiva of Far Rockaway in Far Rockaway, New York.
Yechiel Perr grew up in South Ozone Park, Queens, where his father, Rabbi Menachem Mendel Perr served as a rabbi for over 50 years. Perr attended high school at Mesivta Yeshiva Rabbi Chaim Berlin. After completing high school, he studied at the Talmudical Yeshiva of Philadelphia, and then studied at Beth Medrash Govoha, in Lakewood, New Jersey, under the tutelage of Rabbi Aharon Kotler from 1944 to 1956.
Perr married Shoshana Nekritz, daughter of Rabbi Yehuda Leib Nekritz, granddaughter of Rabbi Avraham Yaffen, and great-granddaughter of the renowned Alter of Novardok, Rabbi Yosef Yozel Horwitz. It was after his marriage that he came into contact with the Novardok tradition. He went on to study at Yeshivat Beis Yosef-Novardok in Brooklyn, New York and at Yeshivas Kaminetz. In 1969, he established the Yeshiva of Far Rockaway, which also runs a high school and an accredited rabbinical studies program.
