Il (, ) was king (, Lugal; ) of the Sumerian city-state of Umma. His father might have been Eandamu, and his grandfather was King Enakalle, who had been vanquished by Eannatum of Lagash. Il was the successor to Ur-Lumma. According to an inscription, before becoming king, he had been temple administrator in Zabalam: "At this time, Il, who was the temple administrator of Zabalam, marched in retreat from Girsu to Umma and took the governorship of Umma for himself." He ruled for at least 12 years.
An alabaster foundation tablet with unknown provenance reads (Uttu, goddess of weaving, has been suggested for TAG.NUN):
He entered in a territorial conflict with Entemena, ruler of Lagash, as mentioned in an inscription:
Il was defeated by Entemena, who had sought the aid of Lugal-kinishe-dudu of Uruk, successor to Enshakushanna, who is in the king list.
Il later fought against Enannatum II, king of Lagash and successor to Enmetena, and defeated him, ending the Lagash dynasty founded by Ur-Nanshe.
He was succeeded by his son, Gishakidu.
