The 32-year-old actor will receive the honour during the annual awards ceremony which will be held at Palm Springs Convention Center on January 2, 2018.
"Gal Gadot's 'Wonder Woman' showed us a strong, capable, poised, curious and compassionate character, and her performance has been universally praised, resonating with audiences everywhere.
"Gal plays the immortal warrior so well, and the film's themes are especially apt for today, empowering all types of people-women and men, young and old-the world over," said festival chairman Harold Matzner in a statement.
The Israel-born actor will reprise her iconic role in "Justice League", alongside Ben Affleck, Henry Cavill, Ezra Miller, Jason Momoa and Ray Fisher, which opens in theatres on November 17.
