Beth Medrash Govoha is a Haredi Jewish Lithuanian yeshiva in Lakewood Township, New Jersey. It was founded by Rabbi Aharon Kotler in 1943 and is the second-largest yeshiva in the world, after Mir Yeshiva in Jerusalem. As of 2019, it had 6,715 students, 2,748 regular and 3,967 in Kollel status. The principal Rosh yeshiva since 1982 is Rabbi Malkiel Kotler. Talmud and halakha studies in the institution are carried in the form of over 200 small groups, Chaburos, which consist of several students mentored by a veteran, each pursuing its own specific curriculum with an emphasis on individual learning.

Haredi Judaism consists of groups within Orthodox Judaism that are characterized by their strict interpretation of religious sources and their accepted halakha and traditions, in opposition to more accommodating or modern values and practices. Its members are usually referred to as ultra-Orthodox in English; however, the term "ultra-Orthodox" is considered pejorative by many of its adherents, who prefer terms like strictly Orthodox or Haredi. Haredi Jews regard themselves as the most religiously authentic group of Jews, although other movements of Judaism disagree.
