This entertainment article ranks the dragons featured in House of the Dragon, the Game of Thrones prequel adapted from George R.R. Martin's Fire & Blood. The series centres on a civil war within House Targaryen over royal succession following King Viserys I's death, with Queen Rhaenyra and King Aegon II competing for the throne. The show has significantly expanded the number of dragons beyond those seen in the original trilogy, using them as key military and political assets throughout the conflict.

The ranking assesses dragons by their combat experience, physical capabilities, and effectiveness in warfare. Lower-ranked dragons like Tessarion show considerable potential despite lacking battle experience, owing to their design and strong bonds with riders. Mid-ranked dragons such as Vermax have proven their value through diplomatic missions and combat operations, though outcomes remain unpredictable in actual warfare. The evaluation reflects how different generations of dragons contribute varying levels of capability to the larger civil war narrative.
