A Chorus Line is a musical with music by Marvin Hamlisch, lyrics by Edward Kleban and a book by James Kirkwood, Jr. and Nicholas Dante. Centred on seventeen Broadway dancers auditioning for spots on a chorus line, the musical is set on the bare stage of a Broadway theatre during an audition for a musical. A Chorus Line provides a glimpse into the personalities of the performers and the choreographer as they describe the events that have shaped their lives and their decisions to become dancers.

Following several workshops and an Off-Broadway production, A Chorus Line opened at the Shubert Theatre on Broadway July 25, 1975, directed and choreographed by Michael Bennett. An unprecedented box office and critical hit, the musical received twelve Tony Award nominations and won nine, in addition to the 1976 Pulitzer Prize for Drama.

The original Broadway production ran for 6,137 performances, becoming the longest-running production in Broadway history until surpassed by Cats in 1997, and the longest-running Broadway musical originally produced in the US, until surpassed in 2011 by Chicago. It remains the sixth longest-running Broadway show ever. A Chorus Line's success has spawned many successful productions worldwide. It began a lengthy run in the West End in 1976 and was revived on Broadway in 2006, and in the West End in 2013.
