Kollel Chazon Ish is a kollel (group of married Jewish men who study Torah) of rabbis on HaAri St 3, in Bnei Brak, Israel with a focus on Talmud study.
The Kollel was originally established by Rabbi Avrohom Yeshaya Karelitz, who was known as the Chazon Ish. Rabbi Yaakov Yisrael Kanievsky, his brother-in-law, taught there.
