Yeshivas Knesses Beis Yitzchak was an Orthodox Jewish yeshiva, founded in Slabodka on the outskirts of Kaunas, Lithuania, in 1897. The yeshiva later moved to Kamyenyets, then part of Poland, and currently in Belarus, and is therefore often referred to as the Kaminetz Yeshiva or simply Kaminetz. The yeshiva was famously led by Rabbi Boruch Ber Leibowitz.
