This article details the discography of Petra. Petra is a music group formed in 1972, and regarded as a pioneer of the Christian rock and contemporary Christian music genres. Though they disbanded formally in 2005, incarnations of Petra have played reunion shows in the years since and released an album in fall 2010. The band released 24 albums (including two live albums, and two Spanish albums) during their 33 years of career starting with their first release in 1974 and finishing with their last album in 2005.

Petra recorded several songs for multi-artist compilation albums that are not available on any of the band's own albums. The band also has songs that were performed only in concert or never recorded for an album.

• "Rocking On with Jesus" (played in concert in the 1970s, never recorded)

This song has recently been recorded by the band GHF (God Has Forgiven) on their album Honestly Live. GHF consists of the original Petra lineup minus Bob Hartman: Greg Hough on guitars and vocals, Bill Glover on drums and vocals, and John DeGroff on bass and vocals.

GHF also played two "reunion" shows with Bob Hartman during Petra's farewell tour.
