Ninḫursaĝ (Sumerian: 𒀭𒎏𒄯𒊕 Ninḫarsang; NIN-ḪAR.SAG̃), sometimes transcribed Ninursag, Ninḫarsag, or Ninḫursaĝa, also known as Damgalnuna or Ninmah, was the ancient Sumerian mother goddess of the mountains, and one of the seven great deities of Sumer. She is known earliest as a nurturing or fertility goddess. She is the tutelary deity to several Sumerian leaders.
Her best-known myths are Enki and Ninhursag describing her dealings with Enki resulting from his sexual exploits, and Enki and Ninmah a creation myth wherein the two deities compete to create humans. She is referenced or makes brief appearances in others as well, most notably as the mother of Ninurta in the Anzû Epic.
