Matt Damon's Daughter Gia Turns 18 at Disneyland

Matt Damon and his family gathered at Disneyland to celebrate his daughter Gia's 18th birthday on Thursday, August 20, 2026. The Oscar winner posed with his wife Luciana and daughters Alexia, Isabella, Gia, and Stella in front of the iconic Mickey Mouse pumpkin on Main Street, U.S.A.

The family donned custom T-shirts for the occasion, with Gia's reading "birthday girl" and the rest of the "birthday crew." This festive visit occurred just before Disneyland's Halloween Time, which commenced on August 21 and runs through October 31, 2026.

Damon recently spoke to PEOPLE about the importance of his family's presence during the strenuous filming of Christopher Nolan's "The Odyssey." He conveyed his gratitude for their sacrifices and support throughout the lengthy production, noting his excitement for his daughters to see the completed film.

Several of Damon's daughters are embarking on their own career paths. Alexia is pursuing a career in film as a photographer and videographer, having worked on "The Instigators." Isabella has signed with IMG Models, signaling her entry into the modeling world.
