Kim Deitch (born 1944) is an American comics artist. He was an important figure in the underground comix movement of the 1960s, regularly contributing comical, psychedelia-tinged comic strips (featuring the flower child "Sunshine Girl" and "The India Rubber Man") to New York City's premier underground newspaper, The East Village Other, beginning in 1967. He became editor of EVO's all-comics spin-off, Gothic Blimp Works, in 1969. He is also an important figure in the current alternative comics movement which evolved from the underground comix movement.
Deitch was also a publisher, as co-founder of the Cartoonists Co-op Press. In 2008, the Museum of Comic and Cartoon Art featured a retrospective exhibition of his work.
Deitch, the son of illustrator and animator Gene Deitch, has sometimes worked with brothers Simon and Seth Deitch.
His best-known character is a mysterious cat named Waldo, who appears variously as a famous cartoon character of the 1930s, as an actual character in the "reality" of the strips, as the demonic reincarnation of Judas Iscariot, and who, occasionally, is claimed to have overcome Deitch and written the comics himself.
Kim Deitch has also worked under the pseudonym Fowlton Means.
