High Society is a 1956 American musical romantic comedy film directed by Charles Walters and starring Bing Crosby, Grace Kelly, and Frank Sinatra. The film was produced by Sol C. Siegel for Metro-Goldwyn-Mayer, and shot in VistaVision and Technicolor, with music and lyrics by Cole Porter.

The film is a musical remake of the 1940 screwball comedy film The Philadelphia Story, which was based on the 1939 play The Philadelphia Story by Philip Barry. High Society's screenplay was written by John Patrick and involves a successful popular jazz musician (Crosby) who tries to win back the affections of his ex-wife (Kelly), who is preparing to marry another man. The cast also features Celeste Holm, John Lund, and Louis Calhern, in his final film, with a musical contribution by Louis Armstrong. The film was Kelly's last professional appearance before she married Prince Rainier III and became Princess consort of Monaco.
