Refael Reuvain Grozovsky (; 1886, Minsk, Belarus – 1958, United States) was a leading Orthodox rabbi, Jewish religious leader and rosh yeshiva ("dean") known for his Talmudic analytical style. Early years He was the son of Rabbi Shimshon Grozovsky, the leading dayan (Halachic judge) of Minsk. He attended Yeshiva Knesses Yisrael, known as the Slabodka yeshiva, and studied under Rabbis Moshe Mordechai Epstein and Nosson Tzvi Finkel. In 1919, Rabbi Grozovsky married the daughter of Rabbi Baruch Ber Lebowitz, whose analytical method of textual study continues to be extremely influential in modern-day yeshivas.

Rabbi Grozovsky was asked by Rabbi Shraga Feivel Mendlowitz to head the Yeshiva Torah Vodaas located in Brooklyn, New York.
