Sweet Charity is a musical with music by Cy Coleman, lyrics by Dorothy Fields and book by Neil Simon. It is based on Federico Fellini's screenplay for Nights of Cabiria. However, where Fellini's black-and-white Italian film concerns the romantic ups-and-downs of an ever-hopeful prostitute, in the musical the central character is a dancer-for-hire at a Times Square dance hall. The musical premiered on Broadway in 1966, where it was nominated for 12 Tony Awards, and also ran in the West End as well as having revivals and international productions.

The show was adapted for the screen in 1969 with Shirley MacLaine as Charity and John McMartin recreating his Broadway role. Bob Fosse directed and choreographed this film.
