The Abbey of San Juan Bautista de Corias (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.
The abbey was founded in 1022 through a donation of land by Count Piñolo Jiménez (Piniolo) and his wife Aldonza Muñoz, wealthy Leonese aristocrats.
The construction of the planned monastery, built in the Romanesque style, was completed in 1043 and a monastic community was established there the following year.
The first abbot was Arias Cromaz, a relative of Piniolo and thus also of Oveco, who was Bishop of Oviedo from 913 to about 960. After 19 years as abbot, Arias was named Bishop of Oviedo by King Alfonso VI of León and Castile. Land disputes a
