The track will be the first single taken from their upcoming sixth studio album, which will be the follow-up to 2008's A Hundred Million Suns.
The single got its first play by BBC Radio 1's Zane Lowe tonight. It will be released as both a single track and as part of an EP on September 4.
The group recorded the song in Topanga Canyon, Los Angeles with long-time collaborator Jacknife Lee.
Snow Patrol's currently-untitled sixth album will also be released later this year.
Lead singer Gary Lightbody recently revealed that R.E.M.'s Michael Stipe helped him overcome writer's block while working on the new album.
