Sin-Iddinam (𒀭𒂗𒍪𒄿𒁷𒈾𒄠, dsuen-i-din-nam) ruled the ancient Near East city-state of Larsa from 1785 BC to 1778 BC. 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.
