Revelation 6 is the sixth chapter of the Book of Revelation or the Apocalypse of John in the New Testament of the Christian Bible. The book is traditionally attributed to John the Apostle, but the precise identity of the author remains a point of academic debate. This chapter describes the opening of the first six of the seven seals. The opening of the seventh seal is recorded in chapter 8. Four horses and their riders, the Four Horsemen of the Apocalypse, emerge as the first four seals are opened.

The Seven Seals of God from the Bible's Book of Revelation are the seven symbolic seals that secure the book or scroll that John of Patmos saw in an apocalyptic vision. The opening of the seals of the document occurs in Rev Ch 5–8 and marks the Second Coming of the Christ and the beginning of The Apocalypse/Revelation. Upon the Lamb of God/Lion of Judah opening a seal on the cover of the book/scroll, a judgment is released or an apocalyptic event occurs. The opening of the first four Seals releases the Four Horsemen, each with his own specific mission. The opening of the fifth Seal releases the cries of martyrs for the "Word/Wrath of God". The sixth Seal prompts plagues, storms and other cataclysmic events. The seventh Seal cues seven angelic trumpeters who in turn cue the seven bowl judgments and more cataclysmic events.
