In the Epic of Gilgamesh, the flood survivor who builds the ark is named Utnapishtim. He receives a warning from the god Ea and constructs a vessel to survive the divine flood.
Utnapishtim’s story appears in Tablet XI of the standard version of the Mesopotamian epic. The episode shares broad motifs with the Noah narrative, including a divinely warned survivor, a large boat, animals, a flood, and birds sent to look for dry land.
The two accounts are not identical. Utnapishtim’s ark is described with different dimensions and construction details, and the surrounding theology belongs to ancient Mesopotamian mythology rather than Genesis. The name is therefore the specific answer when the question shifts from the biblical Noah story to its famous Mesopotamian flood parallel.
