"If Jesus Was a Rockstar" is a song by German singer Kim Petras, released on 11 November 2022 through Amigo and Republic Records.

[2] The song was originally planned to serve as the lead single from Petras' debut studio album Feed the Beast (2023), but it was ultimately dropped from the tracklist.

Petras expected to write the song with just Savan Kotecha and Ilya, but Max Martin was also present when she met with the writers, and he ended up co-writing and producing the song as well as providing backing vocals on it.

[4] Petras also spoke about wanting to "switch things up" from the "gay club music" she had become known for and "sing about something deeply meaningful, something that I struggle with and something that is just honest".

[4] Petras elaborated that "the song kinda says maybe if religion was cooler, then I would wanna be a part of it.
