Sweet Adeline is a 1934 musical film adaptation of the 1929 Jerome Kern/Oscar Hammerstein II Broadway play of the same title.

Sid Barnett, a young composer, is in love with Adeline Schmidt, the daughter of a beer garden owner, but her father Oscar dislikes him, preferring the Spanish-American War hero Major Day.

Because Schmidt is completely opposed to show business, Adeline's sister Nellie runs away to New York, hoping to pursue a career as an actress.

When Day proposes that Adeline become his mistress in return for his support of the play, she is insulted and announces that she will not go on stage after all.

The New York Times critic Andre Sennwald panned the film, writing, "except for the lovely Kern-Hammerstein music and one or two blazing production numbers in the best Warner Brothers style of extravaganza, 'Sweet Adeline' appears to snore in dulcet measures".
