House of the Dragon season 3 premieres on Sunday, June 21, with HBO and Max bringing viewers back to Westeros after a two-year gap. The new season launches at 9 pm ET and will stream on Max alongside its HBO broadcast.
The third season arrives with high expectations because it marks the point where the Targaryen civil war moves from plotting to sustained bloodshed. Despite significant deaths on both sides of the family, the Targaryen civil war has been a bit of a slow burn thus far.
There will be eight episodes in Season 3, airing once a week on Sundays from June 21 to August 9, 2026. The show remains one of HBO’s biggest franchise titles after Game of Thrones, so the release model stays close to the network’s standard Sunday-night prestige slot.
The new season is expected to lean heavily into the Dance of the Dragons, the Targaryen civil war adapted from George R.R. Martin’s Fire & Blood. HBO confirmed in a 2025 production update that season 3 would again feature a large ensemble, including returning stars Emma D’Arcy, Matt Smith, Olivia Cooke, Steve Toussaint, Rhys Ifans, Ewan Mitchell and Tom Glynn-Carney.
Showrunner Ryan Condal has said House of the Dragon is planned to end after four seasons.
