Ur-Ningirsu I

Ur-Ningirsu I (Sumerian:, Ur-D-nin-gir-su), was a Sumerian ruler (ensi) of the state of Lagash in Southern Mesopotamia who ruled c. 2200 BCE. He is much less known and documented than Ur-Ningirsu II, generally just called Ur-Ningirsu.

The existence of Ur-Ningirsu I was proved by an inscription in the British Museum (an offering list, referenced BM 18474), in which he is called "Ur-Ningirsu the elder" (Ur-D-nin-gir-su gu-la), and is contrasted a few lines later by another ruler described as "Ur-Ningirsu, son of Gudea". He would be the son of Ur-Nin-MAR.KI according to the Lagash King List.

Ur-Ningirsu I is also known by a few year names:

"1. "Year: Ur-Ningirsu became ruler" 2. "Year: Ur-Ningirsu became ruler, following year" a. "Year: The š. (priest), found by means of a sacrificial animal" b. "Year: The l. (priest) of Bau, found by means of a sacrificial animal" c. "Year: The i. (priest) of Ningirsu, found by means of a sacrificial animal""
