In the Epic of Gilgamesh, the flood hero who builds a boat is called Utnapishtim.
Utnapishtim appears in the flood narrative of the Epic of Gilgamesh, one of the best-known works of ancient Mesopotamian literature. The god Ea warns him of a coming flood and instructs him to build a large boat, preserve life, and bring aboard living creatures and craftsmen.
After the storm, Utnapishtim sends out birds to determine whether the waters have receded. He eventually makes an offering, and the god Enlil grants him and his wife a special form of immortality. This account shares several motifs with Genesis, including divine warning, a large vessel, survival of living beings, birds, and a post-flood offering.
Utnapishtim is not the same character as Noah. He belongs to Mesopotamian epic tradition, while Noah is the central flood survivor in Genesis. The parallels are important for comparative mythology, but the stories differ in names, details, and theological setting.
