Ur-Nanshe (or Ur-Nina) was the first king of the First Dynasty of Lagash (approx. 2500 BCE) in the Sumerian Early Dynastic Period III. He is known through inscriptions to have commissioned many buildings projects, including canals and temples, in the state of Lagash, and defending Lagash from its rival state Umma. He was probably not from royal lineage, being the son of Gunidu. He was the father of Akurgal, who succeeded him, and grandfather of Eanatum. Eanatum expanded the kingdom of Lagash by defeating Umma as illustrated in the Stele of the Vultures and continue building and renovation of Ur-Nanshe’s original buildings.
He ascended after Lugal-shag-engur (lugal-šag-engur), who was the ensi, or high priest.
Waddell refers to him as Uruash.
