Enentarzi (𒂗𒇷𒋻𒍣, en-en₃-tar-zid, also 𒂗𒂊𒋻𒍣, en-e-tar-zi was Ensi (governor) of Lagash. He was originally a chief-priest of Lagash for the god Ningirsu. He succeed Enannatum II who only had a short reign and was the last representative of the house of Ur-Nanshe. It seems that the power of Lagash waned at this point, and that other territories such as Umma ("Gishban") and Kish prevailed. Enentarzi probably ruled for at least 4 years. An inscription records that 600 Elamites came to plunder Lagash during the rule of Enentarzi, but that they were repelled.
