LOscar al miglior sonoro (Academy Award for Best Sound), precedentemente chiamato Oscar al miglior mixaggio sonoro, viene assegnato al sonoro votato come migliore dall'Academy of Motion Picture Arts and Sciences, cioè l'ente che assegna gli Academy Awards, i celebri premi conosciuti in Italia come premi Oscar. Prima della 93ª edizione dei premi Oscar, l'Oscar al miglior mixaggio sonoro e l'Oscar al miglior montaggio sonoro erano premi separati.
Vincitori e candidati L'elenco mostra il vincitore di ogni anno, seguito dai film che hanno ricevuto una nomination, se possibile con il titolo in italiano.
Gli anni indicati sono quelli in cui è stato assegnato il premio e non quello in cui è stato diretto il film. Nel 1930 si sono svolte due diverse edizioni del premio, una ad aprile ed una a novembre, mentre nel 1933 non è stato assegnato alcun premio.
