Shu-Sin, also Šu-Suen (Akkadian: 𒀭𒋗𒀭𒂗𒍪: DŠuDSîn, after the Moon God Sîn", the "𒀭" being a silent honorific for "Divine", formerly read Gimil-Sin) (died c. 2028 BC) was king of Sumer and Akkad, and was the fourth king of the Ur III dynasty.

He succeeded his father Amar-Sin,[1] and reigned 2037–2028 BC (Middle Chronology).

An erotic poem addressed to Shu-Sin by a female speaker is preserved in a cuneiform tablet called Istanbul 2461.

[2] The poem's speaker expresses her strong desires and longings for the king.

Simanum, Habura, and the surrounding districts rebelled against the king, they chased his daughter away from her residence."
