Slam Dunk has added more names to its stacked 2026 line-up, including Knocked Loose, Boston Manor, and State Champs.
The independent rock festival will be returning next year to celebrate its 20th anniversary at Hatfield Park in Hertfordshire, Saturday May 23, and Temple Newsam in Leeds on Sunday May 24.
The first artists on the line-up were confirmed last month, with Good Charlotte set to headline as a European exclusive performance, and Sublime set to play their first-ever show on these shores.
Others in the initial announcement included President (who are believed to be fronted by Busted’s Charlie Simpson), Taking Back Sunday, Dashboard Confessional, Cancer Bats, Motion City Soundtrack, Hawthorne Heights, Driveways and Tonight Alive.
Now, over 20 new names have been added to the bill, including Kentucky’s own hardcore heavyweights Knocked Loose, who join Good Charlotte and Sublime at the top of the line-up.
A Loss For Words will be back as returning favourites too, as will Baltimore’s Angel Du$t, emo veterans Bayside, rising UK alt-rockers Beauty School, emerging artist Call Me Amour, and punk band Boston Manor.
Hardcore heroes Comeback Kid and Connecticut’s metalcore group Currents also join the line-up for 2026, as do Dying Wish, Guilt Trip, Hands Like Houses, Madina Lake, Static Dress, and former NME Cover stars Heriot. Check out the updated poster above, and visit here to buy tickets.
Celebrating its 20th anniversary in 2025, organisers say that the 2026 edition of the festival will be “it’s biggest and best” instalment yet.
Slam Dunk began as a one-day festival in 2006, headlined by Fall Out Boy, and has grown into one of the biggest independent rock festivals in the UK, with performances over the years coming from the likes of Paramore, Panic! At The Disco, Enter Shikari, Jimmy Eat World, Sum 41 and NOFX.
This year’s Slam Dunk hosted the likes of A Day To Remember, Neck Deep and Alkaline Trio. The festival also launched some additional European legs in 2025, as well as returning to France and Italy.
