Ann Dvorak (August 2, 1912 in film–December 10, 1979) was an American film actress.

Born Anna McKim in New York, New York, Dvorak was the daughter of silent actress Anna Lehr and director and actor Samuel McKim , and as a child appeared in several films. She began working for MGM in the late 1920s as a dance instructor and gradually began to appear on film in small musical roles. Howard Hughes groomed her as a dramatic actress and she was a success in such films as Scarface (1932), as the object of Paul Muni's affection, and opposite Spencer Tracy in Sky Devils (1932).

Known for her style and elegance, she was a popular leading for Warner Brothers during the 1930s, and appeared in numerous contemporary romances and melodramas. A dispute over her pay led to her terminating her contract and working as a freelance artist, but although she worked regularly, the quality of her scripts declined sharply. With her British husband, the actor Leslie Fenton , Dvorak travelled to England where she supported the war effort by working as an ambulance driver, and worked in several British films. She retired in 1951, and lived her remaining years in anonymity, until her death in Honolulu, Hawaii.

Ann Dvorak has a star on the Hollywood Walk of Fame for her contribution to Motion Pictures, at 6321 Hollywood Boulevard.
