The Academy Award for an Actress in a Supporting Role is one of the Academy Awards of Merit presented annually by the Academy of Motion Picture Arts and Sciences (AMPAS) to recognize an actress who has delivered an outstanding performance while working within the film industry. Since its inception, however, the award has commonly been referred to as the Oscar for Best Supporting Actress. While actresses are nominated for this award by Academy members who are actors and actresses themselves, winners are selected by the entire Academy membership.
