Multiple premii pentru "Cea mai bună actriță"

Katharine Hepburn este cea mai premiată actriță, câștigând patru premii. Doisprezece actrițe au câștigat două premii Oscar prntru "Cea mai bună actriță": Ingrid Bergman, Bette Davis, Olivia de Havilland, Sally Field, Jane Fonda, Jodie Foster, Glenda Jackson, Vivien Leigh, Luise Rainer, Meryl Streep, Hilary Swank și Elizabeth Taylor.

Numai două actrițe au câștigat acest premiu în ani consecutivi: Luise Rainer (1937 și 1938) și Katharine Hepburn (1967 și 1968).

Cinci actrițe au câștigat atât premiul pentru cea mai bună actriță cât și cel pentru cea mai bună actriță în rol secundar: Helen Hayes, Ingrid Bergman, Maggie Smith, Meryl Streep și Jessica Lange.

În istoria acestei categorii a existat un singur baraj. Acest lucru a avut loc în 1969, când li s-a atribuit premiul atât actriței Katharine Hepburn cât și actriței Barbra Streisand. Hepburn și Streisand au primit fiecare exact același număr de voturi.

Jennifer Lawrence în vârstă de 22 de ani devine cea mai tânără actriță care câștigă la această categorie, cu rolul ei din Silver Linings Playbook.

Notă: Bette Davis are zece nominalizări. Interpretarea ei din Of Human Bondage nu a fost nominalizată pentru un Oscar. Mai multe persoane influente ale momentului au inclus numele ei pe listă, așa că pentru acel an (și în anul următor, de asemenea) Academia a relaxat regulile și a permis un vot de înscriere. Din punct de vedere tehnic acest lucru a însemnat că orice performanță a fost eligibilă, cu toate acestea, Academia nu recunoaște oficial acest lucru ca o nominalizare pentru Davis.
