Party Girl is a 1958 American film noir directed by Nicholas Ray and starring Robert Taylor, Cyd Charisse and Lee J. Cobb. Filmed in CinemaScope, it was the last film Charisse did for Metro-Goldwyn-Mayer, and the next-to-last film Taylor did for the studio; they were MGM's last two remaining major contract stars.

Nicholas Ray was an American film director, screenwriter, and actor. Described by the Harvard Film Archive as "Hollywood's last romantic" and "one of postwar American cinema’s supremely gifted and ultimately tragic filmmakers," Ray was considered an iconoclastic auteur director who often clashed with the Hollywood studio system of the time, but would prove highly influential to future generations of filmmakers.
