Living It Up is a 1954 American comedy film starring Dean Martin and Jerry Lewis which was released by Paramount Pictures.

The film was directed by Norman Taurog and produced by Paul Jones. The screenplay by Jack Rose and Melville Shavelson was based on the musical Hazel Flagg (1953) by Ben Hecht, which was in turn based on the story "Letter to the Editor" by James H. Street.

An earlier film based on Street's story, Nothing Sacred (1937), had been by Selznick International Pictures (released through United Artists) with Carole Lombard and Fredric March, and directed by William A. Wellman. The 1954 version features original music by Walter Scharf, cinematography by Daniel L. Fapp, art direction by Albert Nozaki and Hal Pereira, and costume design by Edith Head.

In addition to Martin and Lewis, the cast of Living It Up includes Janet Leigh, Edward Arnold, Fred Clark, Sheree North, and Sig Ruman.
