The Academy Award for Best Supporting Actor is an award presented annually by the Academy of Motion Picture Arts and Sciences (AMPAS). It is given in honor of an actor who has delivered an outstanding performance in a supporting role while working within the film industry. The award is traditionally presented by the previous year's Best Supporting Actress winner. At the 9th Academy Awards ceremony held in 1937, Walter Brennan was the first winner of this award for his role in Come and Get It. Initially, winners in both supporting acting categories were awarded plaques instead of statuettes. Beginning with the 16th ceremony held in 1944, however, winners received full-sized statuettes. Currently, nominees are determined by single transferable vote within the actors branch of AMPAS; winners are selected by a plurality vote from the entire eligible voting members of the Academy.Since its inception, the award has been given to 75 actors. Brennan has received the most awards in this category with three awards. Brennan, Jeff Bridges, Robert Duvall, Arthur Kennedy, Jack Nicholson, Claude Rains, and Al Pacino were nominated on four occasions, more than any other actor. As of the 2021 ceremony, Daniel Kaluuya is the most recent winner in this category for his performance as Fred Hampton in Judas and the Black Messiah.
