Amillenialism (or nunc-millennialism) in Christian eschatology is an interpretation of chapter 20 of the Book of Revelation which sees the "1000-year reign" of Christ as non-literal, figurative or symbolic. Amillennialism teaches that the Kingdom of God will not be physically established on earth throughout the "millennium", but rather that the Christian church represents Christ's spiritual kingdom and that Christ is presently reigning from heaven, seated at the right hand of God the Father. Amillennialism is most often associated with Idealism as both teach a very symbolic and spiritualised understanding of many of the prophecies of the Bible and especially the Book of Revelation.

Amillennialism also teaches that the forces of Satan will not be gradually pushed back by the Kingdom of God as history progresses but will remain just as active as always up until the second coming of Christ; therefore good and evil will remain relatively equal in strength throughout history.

Amillennialism was taught by St. Augustine in the fourth century and was a widely held view among Christians throughout Church history. Amillennialism is the official position of the Roman Catholic Church. Amillennialism is also often associated with more conservative Protestants such as those in the Lutheran, Reformed and Anglican churches. Many, but not all, Partial Preterists are Amillennialists. Protestant Amillennialists (and Idealists) have from time to time been accused of over spiritualising parts of the Bible and have been seen by some who take a literal view of much of the Bible as being too "liberal."

Amillennialism stands in contrast to postmillennialism and premillennialism in that some from the former see the "millennium" as literal and others do not, but in the latter almost all see the "millennium" as literal.
