Oscar a la millor actriu

L' Oscar a la millor actriu és una de les categories dels Premis Oscar que anualment entrega l'Acadèmia de les Arts i les Ciències Cinematogràfiques a Los Angeles, Califòrnia. El premi reconeix a l'actriu que ha efectuat la millor interpretació principal de tota la indústria cinematogràfica. Les actrius són nominades pels membres de l'Acadèmia que també es dediquen a l'actuació però, les guanyadores surten elegides dels vots de tots els membres de l'Acadèmia. Amb el sistema actual, una actriu és nominada per una representació específica d'una sola pel·lícula i tals nominacions estan limitades a cinc per any.

Història

En els últims 82 anys, l'Acadèmia ha otorgat un total de 82 Premis a la Millor Actriu Principal a 69 actrius diferents. Les guanyadores d'aquesta categoria reben la familiar estatueta daurada Oscar, que representa a un cavaller armat amb una espasa esperant dempeus sobre un rotlle de pel·lícula de cinc radis. Cada radi simbolitza una de les cinc branques originals de l'Acadèmia: actors, guionistes, directors, productors i tècnics. La primera guanyadora va ser Janet Gaynor, l'any 1928, amb les seves interpretacions a Seventh Heaven, Street Angel i Sunrise: A Song of Two Humans. L'última guanyadora ha estat Natalie Portman, l'any 2010, amb la seva participació a Black Swan.
