Left Behind: A Novel of the Earth's Last Days is a best-selling novel by Tim LaHaye and Jerry B. Jenkins that starts the Left Behind series. This book and others in the series give narrative form to a specific eschatological reading of the Christian Bible, particularly the Book of Revelation inspired by dispensationalism and premillennialism. It was released on Sunday, December 31, 1995. The events take place the day of the Rapture and the two weeks following.

Dispensationalism is a theological framework of interpreting the Bible which maintains that history is divided into multiple ages or "dispensations" in which God acts with his chosen people in different ways. It is often distinguished from covenant theology. These are two competing frameworks of Biblical Theology that attempt to explain the continuity of the Bible as a whole. The term "dispensationalism" is attributed to Philip Mauro, a critic of the system's teachings in his 1928 book The Gospel of the Kingdom.
