It's Always Fair Weather is a 1955 MGM musical satire scripted by Betty Comden and Adolph Green, who also wrote the show's lyrics, with music by André Previn and starring Gene Kelly, Dan Dailey, Cyd Charisse, Dolores Gray, and dancer/choreographer Michael Kidd in his first film acting role.

The film, co-directed by Kelly and Stanley Donen, was made in CinemaScope and Eastmancolor. Although well-received critically at the time, it was not a commercial success, and is widely regarded as the last of the major MGM dance-oriented musicals. In recent years, it has been recognized as a seminal film because of the inventiveness of its dance routines.

It's Always Fair Weather is noted for its downbeat theme, which may have hurt it at the box office, and has been called a rare "cynical musical".
