Tom Terrific was an early animated series on American television, presented as part of the Captain Kangaroo children's television show.

Created by Gene Deitch under the Terrytoons studio, Tom Terrific ran in a series of five-minute cartoons on Captain Kangaroo from 1957-1959, and has occasionally been rerun since.

Amazingly, all the voices were done by one man: Lionel Wilson.

Drawn in a simple, even clumsy, style, it featured a gee-whiz boy hero, Tom Terrific, who lived in a treehouse and could transform himself into anything he wanted thanks to his magic funnel hat. He had a comic lazybones of a sidekick, Manfred the Wonder Dog, and an arch-foe named Crabby Appleton, whose motto was "Rotton to the core!"

The character also appeared in a comic book for six issues in 1957, with some stories drawn by Ralph Bakshi. Tom Terrific also appeared in a few Wonder Books, an imitation of Little Golden Books.
