Altıntepe (Turkish for "golden hill") or Yerez (Armenian: Երեզ) is an Urartian fortress and temple archaeological site dating from the 9th to 7th century BCE.

It is located on a small hill overlooking the Euphrates River in the Üzümlü district of Erzincan Province, Turkey.

During excavations undertaken between 1959 and 1968 and led by Professor Dr. Tahsin Özgüç, a fortified settlement from the Urartian period was found.

In the excavated area a temple or palace, a great hall, a warehouse, city walls, various rooms, and three subterranean chamber tombs on the south side of the hill were found.

After a long gap, excavations were restarted in 2003 by the decision of the Council of Ministers, under the leadership of Professor Dr. Mehmet Karaosmanoğlu.
