Oscar for beste kortfilm (engelsk: Academy Award for Best Live Action Short Film) er en av Oscar-prisene som blir delt ut av Academy of Motion Picture Arts and Sciences (AMPAS). Prisen har vært delt ut hvert år siden den 5. Oscar-utdelingen og ble først delt opp i komedie og nyhetsfilm, og senere i én-rulls-kortfilm (tradisjonell kortfilm) og to-rulls-kortfilm (novellefilm). I 1936 og 1937 ble den også utdelt i en egen fargefilmkategori. Siden 1957 har prisen blitt utdelt i én felles kategori. Det finnes dog en egen priskategori for animerte kortfilmer.
Vinnerne er markert med gul bakgrunn. Årstallet i første kolonne representerer det gjeldende filmåret. Oscar-utdelingen blir vanligvis avholdt året etter.
