Ba Religion is an American punk rock band, formed in Southern California in 1980 by Jay Bentley (bass), Greg Graffin (vocals), Brett Gurewitz (guitars) and Jay Ziskrout (drums). They are often credited for leading the revival of punk rock during the late 1980s, as well as influencing a large number of other punk and rock musicians throughout their career.
