Gilbert Gottfried is an American stand-up comedian, actor and voice actor who voices Mr. Mxyzptlk in Justice League Action. Gilbert Gottfried also voiced Mr. Mxyzptlk previously in Superman: The Animated Series, making him one of the few voice actors from that show to return to a role in a new series.

Gottfried's persona as a comedian features an exaggerated shrill voice and emphasis on crude humor. His numerous roles in film and television include voicing the parrot Iago in Disney's Aladdinanimated films and TV show, Digit in the children's cartoon/educational math-based show Cyberchase, and Kraang Subprime in Teenage Mutant Ninja Turtles. Gottfried was also the voice of the Aflac Duck until 2011. He appeared in the critically panned Problem Child in 1990.

Since 2014, Gottfried has hosted a podcast, Gilbert Gottfried's Amazing Colossal Podcast, which features new episodes each week featuring discussions of classic movies and celebrity interviews, most often with veteran actors, comedians, musicians and comedy writers. Gilbert, a documentary film on Gottfried's life and career, was released in 2017.
