Sin-Iddinam

Sin-Iddinam (, dsuen-i-din-nam) ruled the ancient Near East city-state of Larsa from 1849-1843 BC (MC) or 1785-1778 BC (SC). He was the son of Nur-Adad, with whom there may have been a short co-regency overlap.

The annals for his 7-year reign record that he campaigned against Babylon in year 4, Ibrat and Malgium in year 5, and Eshnunna in year 6.

Sin-Iddinam is also known for a prayer to God Utu, whom he describes as "Father of the black-headed ones".
