Slam Dunk Festival Completes 2026 Line Up & Adds Two New Heavy Stages

The UK’s biggest independent rock festival is gearing up for its biggest party yet. Slam Dunk Festival has just unveiled the second and final wave of acts for its 2026 edition, completing a jaw-dropping line-up that spans pop-punk, emo, metalcore, hardcore, and everything in between.

Headlining alongside Good Charlotte and Sublime are Kentucky hardcore heavyweights Knocked Loose, who will bring their chaotic live show to Slam Dunk for the first time. Joining them are over 20 other massive acts including A Loss For Words, Angel Du$t, Bayside, Beauty School, Boston Manor, Comeback Kid, Currents, Deaf Havana, Dying Wish, Hands Like Houses, Heriot, Madina Lake, Malevolence, Origami Angel, Saosin, State Champs, Trash Boat, Vukovi and many more.

To mark its 20th anniversary, Slam Dunk is going bigger and heavier than ever, with two new side-by-side main stages dedicated entirely to metalcore, hardcore, and post-hardcore and, crucially, zero set clashes. Expect back-to-back chaos as the stages host some of the scene’s most explosive bands, including previously announced heavy hitters like Bury Tomorrow, Cancer Bats and President.

The 2026 festival takes place across the Bank Holiday weekend, hitting Hatfield Park, South, on Saturday 23rd May and Leeds Temple Newsam, North, on Sunday 24th May.
