Who's That Girl: Original Motion Picture Soundtrack is a soundtrack album by American singer-songwriter Madonna, from the film of the same name, and was released on July 21, 1987 by Sire Records. It also contains songs by her label mates Scritti Politti, Duncan Faure, Club Nouveau, Coati Mundi and Michael Davidson. The soundtrack is credited as a Madonna album, despite her only performing four of the nine tracks on the album.
