Christian eschatology is a major branch of study within Christian theology. Eschatology, from two Greek words meaning last (ἔσχατος, last) and study (λογία, lit. discourse), is the study of the end of things, whether the end of an individual life, the end of the age, or the end of the world. Broadly speaking, Christian eschatology is the study of the destiny of humankind as it is revealed by the Bible, which is the primary source for all Christian eschatology studies.

The major issues and events in Christian eschatology are death and the afterlife, Heaven and Hell, the Second Coming of Jesus, the Resurrection of the Dead, the Rapture, the Tribulation, Millennialism, the end of the world, the Last Judgment, and the New Heaven and New Earth of the World to Come. Eschatological passages are found in many places in the Bible, both in the Old and the New Testaments. There are also many extrabiblical examples of eschatological prophecy, as well as church traditions.
