Ukku-Tanhish (also written as: Uk-ku ta-ḥi-eš, Ukkutahieš, Ukku-tahiš, Ukku-Takhesh, and/or Ukkutahesh) was the third king of the Awan dynasty and may have been the third to exercise the kingship of Awan over all of Elam.[1][2][3] He probably reigned sometime in the first Paleo-Elamite period (c. 2400 – c. 2015 BC).[4] Additionally; he could have possibly been the same third king from Awan said on the Sumerian King List (SKL) to exercise the kingship over all of Sumer.[5] According to the SKL: he was preceded by ...Lu and succeeded by Susuda of Kish. However, the Susanian Dynastic List states that he was succeeded by Hishutash.
