拉尔萨（Larsa）是苏美重要的城邦之一，位于乌鲁克东南方25公里的区域，历史可以追溯到前2900前以前。

Larsa (Sumerian logogram: UD.UNUG, read Larsam) was an important city of ancient Sumer, the center of the cult of the sun god Utu. It lies some 25 km southeast of Uruk in Iraq's Dhi Qar Governorate, near the east bank of the Shatt-en-Nil canal at the site of the modern settlement Tell as-Senkereh or Sankarah.
