Stryper is an American Christian metal and heavy metal band from La Mirada, California. The group's lineup consists of Michael Sweet (lead vocals, guitar), Oz Fox (guitar), Perry Richardson (bass), and Robert Sweet (drums).

Formed in 1983 as Roxx Regime, the band soon changed their musical message to reflect their Christian beliefs, and the band's name was also changed to Stryper. They went on to become the first overtly Christian heavy metal band to gain acceptance in the mainstream. In 1983, they signed with major label Enigma Records and released their debut album The Yellow and Black Attack. In the mid-1980s, Stryper enjoyed their most successful period beginning with the release of To Hell with the Devil, which achieved platinum sales status. Stryper went on to release two more gold albums before disbanding in 1993.

In 2003, Stryper came out of retirement for a reunion tour and subsequently signed a multi-album contract with Big3 Records in 2005. In 2013, they signed a multi-album deal with Frontiers Records and have since released Second Coming, which includes 14 re-recorded songs from their first three albums; No More Hell to Pay in 2013; Fallen in 2015; God Damn Evil in 2018; Even the Devil Believes in 2020; The Final Battle in 2022; and When We Were Kings in 2024.
