Hairspray is a musical with music by Marc Shaiman, lyrics by Scott Wittman and Shaiman and a book by Mark O'Donnell and Thomas Meehan, based on the 1988 John Waters film Hairspray. The songs include 1960s-style dance music and "downtown" rhythm and blues. In 1962 Baltimore, Maryland, plump teenager Tracy Turnblad's dream is to dance on The Corny Collins Show, a local TV dance program based on the real-life Buddy Deane Show. When Tracy wins a role on the show, she becomes a celebrity overnight. She then launches a campaign to integrate the show. Hairspray is a social commentary on the injustices of parts of American society in the 1960s.

The musical's original Broadway production opened on August 15, 2002 and won eight Tony Awards out of thirteen nominations. It ran for over 2,500 performances and closed on January 4, 2009. Hairspray has also had U.S. national tours, a London West End production and numerous foreign productions and was adapted for a 2007 musical film. The London production was nominated for a record-setting eleven Laurence Olivier Awards, winning for Best New Musical and in three other categories.
