The discography of Mercyful Fate, a Danish heavy metal band, consists of seven studio releases, three compilations, three singles, and six music videos.

[1] After several line-up changes and self-made demos, Mercyful Fate released their self-titled EP in 1982, with the line-up of King Diamond (vocals), Hank Shermann (guitar), Michael Denner (guitar), Timi Hansen (bass) and Kim Ruzz (drums).

[5] Despite winning a cult following around the world, with sales in the thousands, Mercyful Fate broke up in April 1985, due to musical differences.

[6][7] In 1993, King Diamond, Hank Shermann, Michael Denner and Timi Hansen reunited to reform Mercyful Fate (drummer Kim Ruzz was replaced by Morten Nielsen).

[9] Following the supporting tour, the band released The Bell Witch on 27 June 1994, an EP of live tracks, as well as studio recordings from In the Shadows.
