• A new trailer for House of the Dragon season 3 has been unveiled
• The Game of Thrones prequel is also confirmed to return in late June
• Its next chapter will revolve around of the Targaryen Civil War's bloodiest battles

House of the Dragon season 3 has received a dramatic and fiery new trailer — and an official launch date ahead of its mid-2026 premiere.

Just over two months since House of the Dragon 3's first teaser was released online, HBO has given us a fresh look at the life-threatening events to come in the Game of Thrones prequel's next chapter. At the end of the trailer, it's also confirmed that the high fantasy drama's third season will make its long-awaited debut on June 21, 2026 in North and South America, and June 22, 2026 everywhere else.

Prior to its official release date being publicly announced, we only knew that House of the Dragon season 3 would air sometime in June. With few other big-name TV series set to arrive in the sixth month of the year — currently, Avatar: The Last Airbender season 2, which comes out on Netflix on June 25, is the only other major program set to arrive around that time — it seems House of the Dragon's next installment will have little in the way of competition, too.
