Hairspray is an American musical with music by Marc Shaiman and lyrics by Marc Shaiman and Scott Wittman, with a book by Mark O'Donnell and Thomas Meehan, based on John Waters's 1988 film of the same name.

The songs include 1960s-style dance music and "downtown" rhythm and blues.

Set in 1962 Baltimore, Maryland, the production follows teenage Tracy Turnblad's dream 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, leading to social change as Tracy campaigns for the show's integration.
