"Congregation" is a song by American rock band Foo Fighters. It is the third official single and the second radio single from their eighth studio album Sonic Highways. It was released on October 31, 2014. The song features country music singer Zac Brown, with whom Grohl collaborated with on Zac Brown Band's extended play The Grohl Sessions, Vol. 1.

The song was recorded at Southern Ground Studios in Nashville, Tennessee and featured in the third episode of TV documentary Foo Fighters Sonic Highways which documents the music history of Nashville. The third episode of Foo Fighters Sonic Highways focuses on the country music scene of Nashville that is known as the Nashville sound. Foo Fighters' bassist Nate Mendel told NME that "The song 'Congregation' is a play on how a lot of the folks in the Nashville country music scene came together in church, in a sort of gospel environment, to learn their craft." Foo Fighters' front man Dave Grohl told Q magazine that of the collaboration with Zac Brown: "Zac Brown is an enormous country star. I met him in a store and he asked me to produce an album. I'd never heard of him. I said to someone, Zac Brown has asked me to produce him' - they said, 'You should do it, he's huge' So I did the record without hearing any of his songs." Grohl also explained that the lyrics: "And they're singing like a bluebird in the round," references Nashville's iconic Bluebird Café, stating that "The Bluebird I knew a little bit about, but I learned a lot," explained Grohl. "In Nashville, it seems like there are these rites of passage that you have to go through to become a star, whether you're a singer or a songwriter, and the Bluebird is really one of those. If you can get down at the Bluebird, you've got a gig."

Upon release, Billboard stated that "Congregation" was "the best song from Sonic Highways yet" and that "despite the (Zac) Brown/Nashville connection, "Congregation" is less country and more '70s classic rock -- this is the sound of souped-up car racing down the open highway.
