The Talmudical Institute of Upstate New York (TIUNY) is an all male educational institution for high school and college age young men located in Rochester, New York and 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, grades kindergarten through 8th, with five graduating classes so far.
