Ištaran was a Mesopotamian god who was the tutelary deity of the city of Der, a city-state located east of the Tigris, in the proximity of the borders of Elam. It is known that he was a divine judge, and his position in the Mesopotamian pantheon was most likely high, but much about his character remains uncertain. He was associated with snakes, especially with the snake god Nirah, and it is possible that he could be depicted in a partially or fully serpentine form himself. He is first attested in the Early Dynastic period in royal inscriptions and theophoric names. He appears in sources from the reign of many later dynasties as well. When Der attained independence after the Ur III period, local rulers were considered representatives of Ištaran. In later times, he retained his position in Der, and multiple times his statue was carried away by Assyrians to secure the loyalty of the population of the city.
