Sīn or Suen, or Nannar was the god of the moon in the Mesopotamian religions of Sumer, Akkad, Assyria, and Babylonia. Nannar is a Sumerian deity, the son of Enlil and Ninlil, and became identified with the Semitic Sīn. The two chief seats of Nannar's/Sīn's worship were Ur in the south of Mesopotamia and Harran in the north. A moon god by the same name was later worshipped in South Arabia.
