LOscar al millor documental (en anglès Academy Award for Documentary Feature) és un premi cinematogràfic estatunidenc atorgat cada any, des de 1942 per l'Acadèmia de les Arts i les Ciències Cinematogràfiques, la qual atorga igualment tots els altres Oscars.

Guanyadors i nominats Seguint les normes de l'Acadèmia, les pel·lícules són a la llista sota l'any que han estat seleccionades. A la pràctica, degut a la naturalesa de la distribució dels documentals, una pel·lícula pot sortir en diferents anys, algunes vegades anys després de completar la producció. Els llorejats són indicats al capdavant de cada categoria i en negreta.
