The Cappella San Donato is a small Roman Catholic church or oratory erected in 1500 in the town of Venafro, province of Isernia, region of Molise, Italy.
It was a site for morning prayers for the porcari (swineherdsmen), before they went out into the fields. It was closed during 1920-1942. Damaged during the war, it has not been re-opened.
