The Lomza Yeshiva was an Orthodox Jewish yeshiva in Łomża, Poland, founded by Rabbi Eliezer Bentzion Shulevitz in 1883. Rabbi Yechiel Mordechai Gordon served as the yeshiva's rosh yeshiva for many years, and Rabbi Moshe Rosenstain served as the mashgiach. A branch of the yeshiva was established in Petach Tikvah, Palestine in 1926, where Rabbi Reuven Katz served as co-rosh yeshiva alongside Rabbi Gordon.
