The Abbey of San Juan Bautista de Corias (Asturian: San Xuan Bautista de Courias) is a former Benedictine monastery in Corias in Cangas del Narcea (Asturias), Spain, on the right bank of the Narcea River, dedicated to Saint John the Baptist. Today it is a historic site of the province, informally known as "the Asturian Escorial" (el Escorial Asturiano), due to the burial there of King Bermudo I of Asturias (died 797) and his family.
