Diamond Horseshoe (also billed as Billy Rose's Diamond Horseshoe) is a 1945 American musical film starring Betty Grable, Dick Haymes and William Gaxton (in his final feature film role), directed and co-written by George Seaton, and released by 20th Century Fox.

It was filmed in Technicolor in Billy Rose's Diamond Horseshoe, a nightclub located in the basement of the Paramount Hotel.

The film's original score is by Harry Warren and Mack Gordon, introducing the pop and jazz standard "The More I See You".

During a production number, the bizarre double-talk comic and screeching singer Willie Solar (1891-1956) has a rare onscreen cameo as a filmed record of his stage act.
