Answer:
That depends: Are you talking about on TV or voice actors? Or both? I don't think I could name all of them!!!
Step-by-step explanation:
There is at least three TV actresses for the amazing superheroine:
Cathy Lee Crosby------------------------------- the first television/movie portrayal of the character in 1974.
Lynda Carter---------------------------------------- played the character on her own TV show in 1975 through 1979. (Very good show, by the way.)
Gal Gadot--------------------------------------------- the first blockbuster movie portrayal of the character from 2016 through today. She is in three movies: Batman v. Superman: Dawn of Justice, Wonder Woman, and Wonder Woman 1984; they are all great movies; arguably (and in my opinion) the best portrayal of the character.
Also, Keri Russel is a common voice actor for the amazing Amazon.
And (if you want to) you could count Lily Aspell, who plays a young version of the Amazonian Princess.
Lol hope this helps you know a little bit more about "Wondy" (as Harley Quinn would say it). ✨
