Dreamgirls is a 2006 American musical drama film written and directed by Bill Condon and jointly produced and released by DreamWorks Pictures and Paramount Pictures. Adapted from the 1981 Broadway musical of the same name, Dreamgirls is a film à clef, a work of fiction taking strong inspiration from the history of the Motown record label and its superstar act the Supremes.

The film adaptation features an ensemble cast, starring Jamie Foxx, Beyoncé Knowles and Eddie Murphy with Jennifer Hudson, Danny Glover, Anika Noni Rose and Keith Robinson in supporting roles. In addition to the original compositions by composer Henry Krieger and lyricist Tom Eyen, four new songs, composed by Krieger with various lyricists, were added for the film. The film marks the acting debut of Hudson, a former American Idol contestant.

Dreamgirls debuted in four special road show engagements starting on December 4, 2006, before its nationwide release on December 15, 2006. With a production budget of $80 million, Dreamgirls is one of the most expensive films to feature a predominant African-American starring cast in American film history.
