Frankenstein, Jr. and the Impossibles was an American Saturday morning cartoon produced by Hanna-Barbera Productions in 1966. It premiered on September 10, 1966, and ran for two seasons.

The program contained two segments, which each served as a middle ground between Hanna-Barbera's traditional cartoon early output and its superhero-based late-1960s cartoons.

• Frankenstein, Jr.: Buzz Conroy, a boy scientist, and his father Professor Conroy fight supervillains with the aid of a powerful heroic robot named "Frankenstein, Jr." "Franky", as Buzz usually referred to him, was more than a little reminiscent of the title character in Gigantor; Buzz built "Franky" and activated him through an energy ring.

• The Impossibles: The title characters are a trio of superheroes (Multi Man, Fluid Man, and Coil Man) who pose undercover as a Beatlesesque rock music band. The characters' names are descriptive of their powers: Multi-Man can create identical copies of himself; Coil-Man can form into a super-springy coil; and Fluid-Man can transform his body into any fluid. The heroes receive assignments from "Big D", who contacts them via a receiver in the base of Coil-Man's guitar.

The show was the target of complaints about violence in children's television, and was canceled in 1968. The Frankenstein, Jr. segments were latter recycled in the 1976 series Space Ghost and Frankenstein, Jr., which aired on NBC.

Two cartoons packed into one half hour. Frankenstein Jr. was a robot constructed by a boy-genius to fight crime, The Impossibles were undercover agents disguised as a rock group. Written by Television Junkie
