Herman and Katnip is a series of theatrical cartoons featuring Herman the Mouse and Katnip the Cat, produced by Famous Studios in the 1940s and 1950s. Arnold Stang and Allen Swift were the regular voices of Herman, while Sid Raymond was the regular actor for Katnip, although one or both of the characters would occasionally be voiced by Jackson Beck and Jack Mercer, respectively.

Famous Studios was the first animation division of the film studio Paramount Pictures from 1942 to 1967. Famous was founded as a successor company to Fleischer Studios, after Paramount seized control of the aforementioned studio amid the departure of its founders, Max and Dave Fleischer, in 1942. The studio's productions included three series started by the Fleischers—Popeye the Sailor, Superman, and Screen Songs—as well as Little Audrey, Little Lulu, Casper the Friendly Ghost, Honey Halfwitch, Herman and Katnip, Baby Huey, and the anthology Noveltoons series.
