Altıntepe is an ancient Urartian site located in Üzümlü district of Erzincan Province in the Eastern Anatolia region of Turkey.
Altıntepe is located at the 12th kilometre on the Erzincan to Erzurum highway. The remains are sited on a 60 metre high volcanic hill. During diggings between 1959-1968, by Professor Dr. Tahsin Özgüç, a castle of the Urartian period was found. In this area, a temple (or palace), the great hall, warehouse, city wall, rooms, 3 subterranean rooms sides on south of the hill and an open-air temple were found and excavated. After a break in excavations, they restarted in 2003 with the decision of the Council of Ministers, under the leadership of Professor Dr. Mehmet Karaosmanoğlu.
