Petra is an American music group regarded as a pioneer of the Christian rock and contemporary Christian music genres and was, for many years, regarded as the "world's most popular Christian rock band". Formed in 1972, the band took its name from the Greek word for "rock". Though it disbanded formally in 2006, incarnations have played reunion shows in the years since and released two albums in November 2010, and in November 2017. In 2013, it reformed with a new drummer, Cristian Borneo, and recorded a new song titled "Holy is Your Name", before going back on tour.

Christian rock is a form of rock music that features lyrics focusing on matters of Christian faith, often with an emphasis on Jesus, typically performed by Christian individuals. The extent to which their lyrics are explicitly Christian varies between bands. Many bands who perform Christian rock have ties to the contemporary Christian music labels, media outlets, and festivals, while other bands are independent.
