Gal Gadot sebagai Diana Prince / Wonder Woman:An immortal demigoddess, Amazon princess and warrior. Diana is the daughter of Hippolyta, the Amazonian queen of Themyscira and Zeus, the king of the Olympian Gods. Gadot spoke about the character's evolution, saying in the first film "[Diana] really is a fish out of water, coming from Themyscira into man's world and learning about the complexities of human life, really. In Wonder Woman 1984, she's been around. She's wiser and she's more mature. She's guarded and lost all of her friends throughout the years, but she's still doing the right thing, yet she is different from when we last saw her." Gadot added, "In the first movie, we really explored the journey of the coming-of-age, of how Diana Prince became Wonder Woman and owned her full strengths and powers."
Lilly Aspell reprises her role as young Diana from the 2017 film.
Chris Pine sebagai Steve Trevor: An American pilot and spy from World War I and the love interest of Diana, who had died during the events of the first film. Apparently, he was brought back to life when Diana unknowingly made a wish on the Dreamstone and his soul possesses another man (portrayed by Kristoffer Polaha in the mirror reflections, but only Diana can see his face).
Kristen Wiig as Barbara Minerva / Cheetah:
A highly insecure geologist and gemologist who befriends Diana before becoming imbued with mystical abilities that gradually transform her into an apex predator-like superhuman. She allies herself with Lord to fight Diana.
Pedro Pascal sebagai Maxwell "Max Lord" Lorenzano: A struggling yet charismatic businessman, famous for TV infomercials and the founder of Black Gold Cooperative. Max's character, according to Jenkins, is modeled on Bernie Madoff and Donald Trump. After spending the majority of his life searching for the mythical Dreamstone, Lord acquires it after manipulating Minerva. Lord uses it for personal gain and power and he absorbs its gifts after wishing to become the living form of the stone. Director Patty Jenkins has stated Pascal's performance as Lord was inspired by Gordon Gekko from Oliver Stone's Wall Street and by Gene Hackman's portrayal of Lex Luthor in Richard Donner's 1978 Superman film, with Jenkins describing Lord as "a villain with potential to be dangerous and scary".
