Performance by an Actor 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 actor 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 Actor. While actors are nominated for this award by Academy members who are actors and actresses themselves, winners are selected by the Academy membership as a whole.
