Your guide to Game of Thrones spin-off House of the Dragon season 3
House of the Dragon season 3 is roaring onto our screens this summer. We’re still waiting for an exact date to mark our calendars with, but HBO has confirmed that the next installment of the Game of Thrones spin-off is arriving in a matter of months.
The first season of A Knight of the Seven Kingdoms has now been and gone, so the next stage of the Targaryen civil war will mark our next visit to Westeros. A new teaser trailer hints at what’s next in the Dance of the Dragons as tensions and conflicts intensify between Team Black and Team Green. Season 4 is already in the works, too, so the future of the show is surer than who’s next in line to the Iron Throne.
Below, you’ll find everything you need to know about House of the Dragon season 3, from a list of confirmed cast members, plot speculation based on George R.R. Martin’s source material, and much more besides. Fire and blood await!
House of the Dragon season 3 release date speculation
House of the Dragon season 3 doesn’t currently have an exact release date, but we do know that it’s hitting our screens sometime in June 2026. Season 4, meanwhile, is marked for 2028.
Is House of the Dragon season 3 the final season?
No, House of the Dragon season 3 won’t be the final season – but season 4 will be. Showrunner Ryan Condal confirmed that things will wrap up after four seasons in a press conference after the season 2 finale and HBO boss Casey Bloys confirmed the news in February 2026.
“The idea has always been to follow the history of the Targaryens. If you know the books, you know how the Targaryens end up. So there is a natural end to this particular history of that House of the Targaryens,” he said.
