Superkatt is an American cartoon animal comic book series by Dan Gordon (under the comics pen name "Dang"), a jab at the “long-underwear” genre of superhero comics. The series stars Superkatt, an anthropomorphic cat who wears a bowtie, bonnet, and diaper as a superhero costume. Ron Goulart, author of Ron Goulart's Great History of Comic Books, said that Superkatt was Dang's most memorable comic book character. Denis Gifford, author of The International Book of Comics, said that the character "was as silly as his supercostume."

Superkatt was an ordinary housecat who thought that he had superpowers, although all he did was drink vitamin milk. However, he did often successfully (if accidentally) defeat his enemies; at one point, he captures a U-boat.

Superkatt first appeared in American Comics Group's Giggle Comics #9 in 1944. The series was a regular feature in Giggle until 1955, when creator Gordon returned to the animation field. The character also made an appearance in ACG's series Ha-Ha Comics in 1946.

In 1947, Superkatt appeared in the animated short Leave Us Chase It, a part of the Phantasies series. A cat, who is being tormented by a mouse, reads a comic book and receives inspiration from it, so he dresses up as Superkatt and decides to fight back. The cat was voiced by Bill Shaw.
