Ann Reinking (born November 10, 1949 in Seattle, Washington) is an American actor and dancer who made her mark on Broadway, creating the role of "Maggie" in the Sherman Brothers musical, Over Here!. She appeared in the Broadway cast of Pippin and A Chorus Line and made her movie debut in 1979 in All That Jazz in the role loosely based on herself and her relationship with Bob Fosse. In the film, Reinking starred opposite Leland Palmer (playing a role inspired by Fosse's wife, Gwen Verdon), Jessica Lange, Ben Vereen, John Lithgow, and Roy Scheider as Bob Fosse. In a case of life imitating art, Reinking was actually in a long term relationship with Fosse for many years before his death.
Reinking later went on to star in films like Annie and Micki and Maude. She then focused her career on choreography for Broadway musicals. She has won Tony awards for Best Choreography in a musical, Golden Desk awards, and even the Bob Fosse award. Her latest choreography work is for the Broadway musical Chicago.
In May of 2005, Mad Hot Ballroom was released. In the documentary, Reinking is featured as one of the enthusiastic judges of the annual New York City public school dance competition for inner city youth.
