Eddie Deezen (March 6, 1957 - November 8, 2026) was an American character actor, voice actor and comedian, best known for his bit parts as nerd characters in 1970s and 1980s films such as Grease, Grease 2, Midnight Madness, 1941 and WarGames, as well as for larger roles in a number of independent cult films, including Surf II: The End of the Trilogy and I Wanna Hold Your Hand.
As a voice actor, he is easily recognizable for his distinctively high-pitched and nasally voice, most notably used for the characters of Mandark in the Cartoon Network series Dexter's Laboratory, Snipes the Magpie in Rock-A-Doodle, Ned in Kim Possible and Lenny the Know-It-All in The Polar Express. He passed away from a motor neurone disease.
