Best Actress in a Supporting Role is a British Academy Film Award presented annually by the British Academy of Film and Television Arts (BAFTA) to recognize an actress who has delivered an outstanding supporting performance in a film.
No award was given out in this category in 1980, when no actors, male or female, were nominated for supporting roles.
The first winner was Billie Whitelaw for her roles in Charlie Bubbles and Twisted Nerve.
The most recent winner is Da'Vine Joy Randolph for her role in The Holdovers.
At the 36th BAFTA Film Awards, Rohini Hattangadi and Maureen Stapleton received the same number of votes and thus both shared the award in this category's only tie.
