Playing their first Bristol show in 14 years, the band will perform at the Canons Marsh Amphitheatre on July 23, as part of the three-day Harbourside event.
Tom Hoyle, co-founder of the Siren series, said: “We’re buzzing to have The Maccabees kick things off for Siren 2026.
“Their return has been such a moment and having them play on the Harbourside in the middle of summer, it’s going to be proper feel-good from start to finish.
“One of those shows you’ll be talking about all year.”
The alternative rock group will play one of just five UK outdoor shows scheduled for next summer.
Fans can expect a setlist featuring tracks from their Mercury Prize-nominated album Given to the Wild and the chart-topping Marks to Prove It, along with earlier favourites from Colour It In.
