Hugo Treffner Gymnasium (Estonian: Hugo Treffneri Gümnaasium; abbreviated as HTG) is a secondary school in Tartu, Estonia with special emphasis on science education. Founded by Hugo Treffner, it was the only large secondary school in 19th-century Estonia with predominantly Estonian students and no age restrictions. During the Estonian national awakening, it greatly contributed to the numbers of Estonian intellectuals.
