Tonight and Every Night is a 1945 American musical film directed by Victor Saville and starring Rita Hayworth, Lee Bowman and Janet Blair. The film portrays wartime romance and tragedy in a London musical show, loosely modelled on the Windmill Theatre in Soho, that determined not to miss a single performance during the Blitz. Hayworth plays an American showgirl who falls in love with an RAF pilot played by Bowman.

The film was adapted from the play Heart of a City by Lesley Storm. It was used as a Technicolor vehicle for Rita Hayworth after her success with Cover Girl. It was nominated for two Academy Awards: Best Music, Original Song (for "Anywhere") and Best Music, Scoring of a Musical Picture. A major highlight of the film is Hayworth in the "You Excite Me" number, a number often cited as one of Hayworth's best performances.
