In the Epic of Gilgamesh, the flood survivor comparable to Noah is named Utnapishtim.
Utnapishtim appears in the flood story told in Tablet XI of the Epic of Gilgamesh. The god Ea warns him of a coming flood, and Utnapishtim builds a large boat, preserves life, and survives the catastrophe.
The story shares broad motifs with the Genesis narrative, including divine warning, a vessel, a flood, survival, and the release of birds. Utnapishtim’s account is part of Mesopotamian literature and is not simply another name for Noah.
Atrahasis is another Mesopotamian flood hero from a related but separate tradition. Because the stories have overlapping elements, readers sometimes confuse Utnapishtim and Atrahasis. In the Gilgamesh epic specifically, the survivor is Utnapishtim.
