Nam-mahani (Sumerian: {{cuneiform|, nam-maḫ-ni)[1] was a Sumerian ruler, and the last ensi of Lagash circa 2100 BCE (middle chronology), roughly contemporaneous with the last king of Akkad, Shu-turul.[2] [3] His reign was followed by that of Utu-hengal, who destroyed the power of the Gutian Dynasty, and put and end to the power of the various city-states, reunifying the Sumerian realm.
Nam-mahani is known from various inscriptions,[4] and especially a macehead dedicated by queen Nininimgina and bearing the name of King Nam-Mahani, to god Kindazi:[5]
