The Kovno Kollel also known as Kollel Perushim of Kovno or Kollel Knesses Beis Yitzchok, was a kollel located in Kaunas, Lithuania. It was founded in 1877 by Rabbi Yisrael Lipkin Salanter when he was 67. In 1880, Finkel left the kollel so he could devote himself to establishing more kollelim throughout Eastern Europe. In 1880, Spektor also left the Kollel, and Salanter's student Yitzchak Blazer became its new head. Under Blazer's direction, the kollel came to be "considered by its contemporaries as a bastion of the Mussar movement," and was attacked by the Mussar movement's opponents.
