Chicago is a Kander and Ebb musical set in prohibition era Chicago. The book is by Ebb and Bob Fosse. The story is a satire on corruption in the administration of criminal justice, and the concept of the "celebrity criminal." The musical is based on a 1926 play of the same name by reporter Maurine Dallas Watkins about actual criminals and crimes she had reported on.

The original 1975 Broadway production ran for a total of 936 performances. Bob Fosse choreographed the original production, and his style is strongly identified with the show. Chicago's 1996 Broadway revival holds the record for the longest-running musical revival on Broadway (not counting the revue Oh! Calcutta!) and, as of March 2, 2008, it has played for more than 4,684 performances. The revival was followed by a production on London's West End and several tours and international productions. An Academy Award-winning film version of the musical was released in 2002.
