How to Succeed in Business Without Really Trying is a musical with music and lyrics by Frank Loesser and book by Abe Burrows, Jack Weinstock, and Willie Gilbert, based on Shepherd Mead's 1952 book of the same name.

The musical opened at the 46th Street Theatre on Broadway in October 1961, running for 1,417 performances. The show won seven Tony Awards, the New York Drama Critics Circle award, and the 1962 Pulitzer Prize for Drama. In 1967, a film based on the musical was released by United Artists, with many of the original cast recreating their roles. A 1995 revival was mounted at the same theater as the original production (now named the Richard Rodgers Theatre), and ran for 548 performances, and starred Matthew Broderick and Megan Mullally.
