Organisers of the annual music event, which takes place from August 17 until 19 at Funkirk Estate in the Yorkshire Dales, recently announced that Jessie Ware and Frankie and the Heartstrings will also be playing at the festival.
The Beacons Festival Twitter page read: "We are more than delighted to announce that the incredible Mercury Prize Nominees @WildBeasts will be our Saturday night headliner!"
The band later took to their page on the microblogging site, writing: "We're late in announcing this, but we're playing the new, excellent Beacons festival this year @BEACONSFEST."
The event will also feature acts such as Junior Boys, Errors, Factory Floor, Jane Coles and Roots Manuva.
Last year's Beacons Festival was cancelled after local authorities inspected the site and said that it was "no longer considered to be safe for a public audience" due to adverse weather conditions.
