The band will release 'This Isn't Everything You Are' on November 13, a day ahead of their sixth studio album Fallen Empires.
It is the second song to be lifted from the forthcoming LP and follows their recent song 'Called Out In The Dark', which became their fastest-selling single ever.
The group performed 'This Isn't Everything You Are' on Later... with Jools Holland earlier this month.
Snow Patrol will perform at the Q Awards at the HMV Forum in London on October 27.
The band will then play a handful of shows in Dublin and Belfast after Christmas, performing their new material for fans.
More UK dates will be announced in the coming weeks. Fans who pre-order Fallen Empires through the official store will have the chance to enter an exclusive ticket pre-sale.
