House of the Dragon Season 3 premieres June 21 on HBO and Max

The prequel series *House of the Dragon* returns with its third season on Sunday, June 21, 2026, on HBO in the United States. Episodes will air weekly for eight weeks, concluding in early August. In France, the season will be available a day later on the streaming platform Max, with new episodes released each Monday.

The eight‑episode arc continues the Targaryen civil war known as the Dance of the Dragons, focusing on the full‑scale clash between the Black and Green factions, including a major naval‑aerial battle at the Gosier. The trailer highlights massive set pieces, dragon battles, and the driving ambition of Rhaenyra Targaryen, portrayed by Emma D'Arcy, who vows to seize King’s Landing.

The core cast returns—Emma D'Arcy, Matt Smith, Olivia Cooke, and others—joined by newcomers such as James Norton and Tommy Flanagan. Showrunner Ryan Condal and executive producer George R.R. Martin confirm this season will be the penultimate chapter before the series concludes with season four.
