who is jace's dad house of the dragon

Jace’s dad in House of the Dragon is Laenor Velaryon. Jace is officially his son in the story, though the show strongly suggests that his biological father is actually Harwin Strong.

Quick Scoop

• Officially: Laenor Velaryon is Jace’s father.

• In practice: the series implies Jace is one of Rhaenyra’s sons by Harwin Strong.

• Why it matters: it’s one of the main political secrets driving the conflict in the show.

The family tree confusion is intentional, since House of the Dragon revolves around legitimacy, inheritance, and who is publicly recognized versus who is actually the biological parent.

TL;DR: Jace’s legal dad is Laenor Velaryon, but his likely biological dad is Harwin Strong.
