《启示录》（希腊语：ΑΠΟΚΑΛΥΨΙΣ ΙΩΑΝΝΟΥ；天主教《思高圣经》汉译作《若望默示录》），是《新约圣经》中收录的最后一个作品。作者拔摩岛的约翰，基督教会传统上相信即是耶稣的门徒约翰。主要是对未来的预警，包括对世界末日的预言：接二连三的大灾难，世界朝向毁灭发展的末日光景，并描述最后审判，重点放在耶稣的再来。

“启示”一词在希腊文为“阿波卡利普西斯”（Αποκάλυψις，a‧po‧ka′ly‧psis），意思是揭示、揭开之意。

The Book of Revelation, often known simply as Revelation or The Apocalypse of John, is a book of the New Testament that occupies a central place in Christian eschatology. Its title is derived from the first word of the text, written in Koine Greek: apokalypsis, meaning "unveiling" or "revelation". The Book of Revelation is the only apocalyptic document in the New Testament canon (although there are short apocalyptic passages in various places in the Gospels and the Epistles).
