The Academy Award for Best Actress is an annual award presented by the Academy of Motion Picture Arts and Sciences (AMPAS) to recognize outstanding performances by female actors in leading roles. It is one of the most prestigious awards in the film industry and is part of the larger Academy Awards ceremony, commonly known as the Oscars. The award has been given since 1927, with the first recipient being Janet Gaynor for her performances in three films. Nominees are selected by members of the Academy, and the winner is determined through a voting process, celebrating excellence in cinematic storytelling and acting.
