The garden where Adam and Eve lived was the Garden of Eden.
In Genesis, God places Adam in Eden and appoints him to cultivate and protect the garden. Eve is later created as Adam’s companion, and the pair live there among abundant plants and trees. The story identifies two special trees: the Tree of Life and the Tree of the Knowledge of Good and Evil.
Genesis describes Eden as watered by a river that divides into four branches: the Pishon, Gihon, Tigris, and Euphrates. Because two of those rivers are known from real geography, later writers and explorers proposed locations in Mesopotamia, Armenia, and elsewhere, but no historical location has been established.
A common mix-up is treating “Eden” and “the Garden of Eden” as exactly interchangeable in every context. Eden is the broader biblical place-name, while the garden is the particular paradise described in Genesis. Adam and Eve are expelled after eating from the forbidden tree, making Eden central to the biblical account of humanity’s fall.
