The Foxboro Hot Tubs are an American garage rock band.

The group made its first appearance on the music scene in December 2007, debuting three songs on its website, www.foxborohottubs.com . Soon after, Foxboro Hot Tubs were discovered and subsequently made headlines, being heralded as the next secret side project of Green Day, which was later confirmed by the band themselves.

The Foxboro Hottubs are Jason White, Jason Freese, Michael Pritchard, Frank Edwin Wright the Third and the Reverend Strychnine Twitch. “ ... We are four guys who love to play music and be spontaneous, [and] after a few late night jams and a few too many bottles of wine, we were inspired to record some rockin' eight-track recordings."

For those who didn't know, Green Day bassist Mike Dirnt's real name is Michael Pritchard, and drummer Tre Cool was born Frank Edwin Wright III. We're just going to assume that "Strychnine Twitch" is the alter ego Armstrong has adopted for the Hot Tubs project (it's also a lyric in Foxboro's tune "Stop Drop and Roll").

Freese and White have both played on Green Day's recent albums, and White is also a member of Armstrong's side project, Pinhead Gunpowder.
