Atrahasis is the Mesopotamian flood hero named in the Epic of Atrahasis who parallels Noah.
The Epic of Atrahasis is an Akkadian poem preserved on clay tablets from the second millennium BCE. In its flood narrative, the god Enki warns Atrahasis about a coming catastrophe and tells him to build a boat. Atrahasis takes aboard his family, craftsmen, and animals, surviving while the flood destroys the wider population.
The account shares major elements with Genesis, but its divine motives and narrative details differ. It is one of several ancient Near Eastern flood traditions, alongside the Sumerian story of Ziusudra and the Epic of Gilgamesh's account of Utnapishtim.
These names are easy to confuse because later versions preserve related plot patterns and may derive from older traditions. Atrahasis is the hero of the work bearing his name; Utnapishtim is the corresponding survivor in the Epic of Gilgamesh, while Noah belongs to Genesis.
