The Prix Iris for Best Sound (French: Prix Iris du meilleur son) is an annual film award presented by Québec Cinéma as part of the Prix Iris awards program, to honour the year's best sound in feature films made within the Cinema of Quebec. Unlike some film awards, Québec Cinéma does not present separate awards for overall sound and sound editing, but instead honours the full sound team in a single category; however it does also present a distinct category for Best Sound in a Documentary.
