Johnny Doesn't Live Here Anymore is a 1944 American romantic comedy film starring Simone Simon, James Ellison, William Terry, and featuring Robert Mitchum in an early role. Produced by King Brothers Productions, it was co-written by Philip Yordan and directed by the Austrian director Joe May, and constitutes the final film directed by Joe May. It was based on a short story purchased by the King Brothers. The film has fantasy elements, with the main character being followed by a gremlin.

The film's interest and charm derives in large part from its extremely varied cast of supporting players. Although Robert Mitchum's role in the film has come to be emphasized for marketing purposes, he was not yet a star and only appears in the last twenty minutes or so of the film. Horror film staple Rondo Hatton speaks no lines and gets a laugh merely by appearing on screen briefly in a surprise appearance. Billy Laughlin, playing a child who lives in Simon's apartment building, was far better known at the time as "Froggy" in the Our Gang shorts, his only other film work also with a regular voice.
