The Yeshiva of Rochester (formerly the Talmudical Institute of Upstate New York or TIUNY) is an all-male educational institution for high school- and college-age young men located in Rochester, New York. It is primarily an American, Lithuanian style Haredi but non-Hasidic yeshiva. TIUNY was founded in 1974 as the first external affiliate branch of the Chofetz Chaim education network by Rabbi Menachem Davidowitz and Rabbi Dovid Harris.
In 2004, TIUNY opened its own day school, Derech HaTorah of Rochester, offering grades kindergarten through 8th.
