House of the Dragon is expected to run for 4 seasons total. HBO confirmed the series will end with Season 4, and Season 3 is currently airing in June 2026.

What that means

  • Season 1 and Season 2 have already aired.
  • Season 3 premiered on June 21, 2026.
  • Season 4 is planned as the final season.

Quick note

That’s the current official plan, so unless HBO changes course later, the answer is four seasons. TL;DR: 4 seasons total.
