"Bro Hymn" is a song by American punk rock band Pennywise. It is the last track on both their 1991 self-titled debut album, and 1997's Full Circle as "Bro Hymn (Tribute)". Its lyrics are about the death of bassist Jason Thirsk's friends Tim Colvin and Carlos Canton (who both died in separate motorcycle accidents), and Tom Nichols (who drowned at Hermosa Beach Pier in 1988).

In 1996, following the death of Thirsk, "Bro Hymn" was recorded again for their fourth album Full Circle as "Bro Hymn Tribute", which is dedicated to him. On this version, one of the lines from the original, "Canton, Colvin, Nichols, this one's for you", is replaced with "Jason Matthew Thirsk, this one's for you". In addition, "To all my friends" was replaced with "To our best friend", "Especially those who weren't with us too long" was replaced with "Though you weren't with us too long," in reference to Thirsk being the band's first bassist, "Life is the most precious thing you can lose" having the words "is" and "you can" being replaced with "was" and "we could", and the final "Canton, Colvin, Nichols, this one's for you" being replaced with "Jason, my brother, this one's for you". This version of "Bro Hymn" was not a hit song on the charts, but today receives substantial radio play.

When Pennywise perform the song live, they mix the lyrics from the original and "Tribute".

Bassnectar's song "Pennywise Tribute" on his Vava Voom album is a remix of "Bro Hymn (Tribute)".
