Helena Shaw is Indiana Jones’s goddaughter in Indiana Jones and the Dial of Destiny, not his daughter.
The film introduces Helena as the daughter of Basil Shaw, an archaeologist and former wartime colleague of Indiana Jones. She seeks the Antikythera, a device designed by the ancient Greek mathematician Archimedes, and draws Indiana into a globe-spanning pursuit.
Phoebe Waller-Bridge plays Helena, while Toby Jones portrays Basil Shaw. Helena’s close relationship with Indiana is central to the story, but the film does not establish her as his biological child.
A common mistake is to call Helena Indiana’s daughter because she functions as a younger family successor. Indiana’s known biological son is Mutt Williams, introduced in Kingdom of the Crystal Skull.
