House of the Dragon Season 3 premieres June 21

HBO said on April 27 that the third season of “House of the Dragon” will premiere on Sunday, June 21, 2026, at 9:00 p.m. ET/PT on HBO and HBO Max. Warner Bros. Discovery said the season will consist of eight episodes released weekly through August 9. The announcement gives the “Game of Thrones” prequel a fixed return date after HBO had previously said only that the season would arrive in summer 2026. (press.wbd.com) Warner Bros. (press.wbd.com) Discovery’s press materials also set out how the rollout will work. The company said the series will air on HBO and be available to stream on HBO Max, continuing the adaptation of George R.R. Martin’s “Fire & Blood.” HBO’s property page for the show lists the same April 27 release, repeating the June 21 launch date and weekly schedule.

The company said the season will debut on the HBO cable network and stream on HBO Max the same day. (press.wbd.com) May 21 press materials for HBO Max’s June lineup repeated that timing in a broader monthly release slate. Art Threat separately reported the same date in coverage of HBO Max’s June programming, but the HBO and Warner Bros. Discovery press releases provide the primary confirmation. (press.wbd.com) ### How many episodes are in the new season? The third season will have eight episodes, according to HBO’s April 27 release. Warner Bros. Discovery said new installments will air weekly, with the finale scheduled for August 9. That episode count matches an earlier production update from the company, which said season three began filming in the United Kingdom as an eight-episode season. (press.wbd.com) The production notice also listed returning cast members including Matt Smith, Emma D’Arcy and Olivia Cooke. (press.wbd.com) ### What has HBO said about the show’s longer-term plan? HBO said in a November 2025 franchise renewal announcement that “House of the Dragon” had already been renewed for a fourth season. The company said at the time that season three would debut in summer 2026 and season four in 2028. (press.wbd.com) The June 21 date now fills in the schedule HBO had previously outlined in broader terms. Art Threat reported that season four has been positioned as the show’s final season, but the official Warner Bros. Discovery release reviewed here confirms the renewal and 2028 target rather than that additional characterization. (press.wbd.com) ### Will there be any new accessibility options on HBO Max? HBO Max said on May 21 that “House of the Dragon” will be available in American Sign Language. The company said season three with ASL will launch alongside the June 21 debut, while season one with ASL arrives on May 29 and season two on June 15. (press.wbd.com) Global Accessibility Awareness Day was the occasion HBO Max cited for that announcement. The June programming release repeated the same dates, making the ASL rollout part of the platform’s broader June slate. ### What happens next on the release calendar? (press.wbd.com) May 29 is the first upcoming date in HBO Max’s accessibility rollout, when season one in ASL becomes available, followed by season two in ASL on June 15. The main season-three premiere is set for June 21 at 9:00 p.m. ET/PT, and HBO said the eight-episode run will conclude on August 9. (press.wbd.com 1) (press.wbd.com 2)
