Sensations of 1945 is a 1944 American musical-comedy film directed by Andrew Stone and starring Eleanor Powell. Released by United Artists, the film was an attempt to recapture the ensemble style of films such as Broadway Melody of 1936 by showcasing a number of top musical and comedy acts of the day, in a film linked together by a loose storyline. Sensations of 1945 stars dancer Powell and Dennis O'Keefe as two rival publicists who fall in love, but the film's main purpose is to showcase a variety of different acts, ranging from tightrope walking to comedy to Powell's athletic tap dancing. The rollicking supporting cast features W.C. Fields in his final role the year before his death, C. Aubrey Smith, Eugene Pallette, dancer David Lichine, Lyle Talbot, Sophie Tucker, jazz pianist Dorothy Donegan, Cab Calloway, Woody Herman, jazz pianist/composer Gene Rodgers, and Les Paul.

The picture is notable for several reasons. It was Powell's first and only film after leaving Metro-Goldwyn-Mayer, where she became a star nearly a decade earlier; it was also her final starring role in a film, after which she would only make a cameo in MGM's Duchess of Idaho in 1950 and some unused footage of her would appear in a 1946 MGM compilation, The Great Morgan. Powell's dance inside a giant pinball machine (as part of the song, "Spin Little Pinball") has been cited by critics variously as both a highlight and as the nadir of her film career.

The film was nominated for an Academy Award for Best Music Scoring.
