"After Forever" is a song by English rock band Black Sabbath. The song was released on their third studio album Master of Reality in 1971, the lyrics were written by Geezer Butler while the music was written by Tony Iommi.

Although the album jacket credits Iommi alone as the composer of this song (including lyrics), the Black Sabbath Black Box Set refutes the album jacket credit and gives credit to this song (along with "Orchid" and "Embryo") to all four band members in keeping with their wishes to remain a democratic band.

The lyrics of "After Forever," written by Geezer Butler,^[1] who was brought up strictly Catholic, focus entirely on Christian themes.^[2] At the time, some such as religious and conservative groups viewed Black Sabbath as Satanists (which the band had consistently denied) due to their dark sound, image and lyrics, with occultism and horror as a recurring theme.
