What is the name of the Babylonian flood story that includes Utnapishtim?

The Babylonian flood story that includes Utnapishtim appears in the Epic of Gilgamesh.

The flood episode is found in Tablet XI of the standard version of the Epic of Gilgamesh. In it, Utnapishtim recounts how the god Ea warned him to build a boat and preserve life before a devastating flood. The king Gilgamesh hears the story while seeking the secret of eternal life.

The Epic of Gilgamesh is one of the oldest surviving works of literature. Its best-known form is written in Akkadian on clay tablets, while earlier Sumerian stories about Gilgamesh also survive. The flood account has notable parallels with Genesis, but it belongs to a different Mesopotamian literary and religious tradition.

The Enuma Elish is another major Babylonian composition, but it is a creation epic rather than the work containing Utnapishtim’s flood narrative. Hammurabi’s Code is a law collection, not a flood story.
