O Days Festival has officially unveiled its 2026 lineup, confirming the electronic and alternative-focused event will return to Sonder Hoved at Refshaleoen in Copenhagen from 30th July - 1st August, 2026. Known for its cutting-edge curation and intimate industrial setting, O Days continues to position itself as a must-attend summer festival for forward-thinking dance music fans across Europe.

Leading the 2026 bill is Disclosure, set to deliver a DJ set alongside heavyweight selectors and live electronic favourites. Joy Orbison, Mall Grab and Nia Archives bring a powerful blend of club culture, bass and breakbeat energy, while The Dare and Yaeji both appear in DJ set formats. The announcement signals a strong emphasis on dancefloor-driven programming, with a clear focus on contemporary electronic sounds.

The lineup also features a deep supporting cast including Bremer/McCoy, Courtesy, Elsked, Jodie Harsh and Mona Moroni, alongside Rose Gray, Swank Mami, Swimming Paul, Tripolism, Von Quar and Σtella. With more artists still to be announced, the initial drop highlights O Days’ commitment to showcasing both internationally recognised names and emerging talent from across the electronic spectrum.

Three-day tickets for O Days 2026 are already on sale, giving fans the chance to lock in their spot early for the Copenhagen summer event. With its first lineup reveal now live and further announcements on the way, O Days is shaping up for another standout edition in 2026.
