The Book of Exodus or, simply, Exodus, (from Greek ἔξοδος, Exodos, meaning "going out"; Hebrew: שמות‎, Šemot, "Names") is the second book of the Hebrew Bible, and of the five books of the Torah (the Pentateuch). The Greek and English name originates with the Septuagint translation of the 3rd century BCE.

The book tells how the children of Israel leave slavery in Egypt through the strength of Yahweh, the God who has chosen Israel as his people. Led by their prophet Moses they journey through the wilderness to Mount Sinai, where Yahweh promises them the land of Canaan (the "Promised Land") in return for their faithfulness. Israel enters into a covenant with Yahweh who gives them their laws and instructions for the Tabernacle, the means by which he will dwell with them and lead them to the land.

Traditionally ascribed to Moses himself, modern scholarship sees the book as initially a product of the Bablyonian exile (6th century BCE), with final revisions in the Persian post-exilic period (5th century). Carol Meyers in her commentary on Exodus suggests that it is arguably the most important book in the bible, as it presents the defining features of Israel's identity: memories of a past marked by hardship and escape, a binding covenant with the God who chooses Israel, and the establishment of the life of the community and the guidelines for sustaining it.
