Guys and Dolls is a musical, with the music and lyrics written by Frank Loesser and book by Jo Swerling and Abe Burrows, based on "The Idyll of Miss Sarah Brown" and "Blood Pressure", two short stories by Damon Runyon. It also borrows characters and plot elements from other Runyon stories, most notably "Pick the Winner".

The musical was first produced on Broadway at the 46th Street Theatre, opening on November 24, 1950 and directed by George S. Kaufman. It starred Robert Alda, Sam Levene, Isabel Bigley, and Vivian Blaine. The play enjoyed an initial run of 1,201 performances, winning five 1951 Tony Awards, including the award for Best Musical. Decca Records issued an original cast recording on LP; it was later reissued on CD by MCA. The original London production opened at the London Coliseum on May 28, 1953 and ran for 555 performances. The show enjoyed numerous award-winning revivals and tours and has become a popular choice for school and community theatre productions.
