Ribeira Sacra is a Spanish Denominación de Origen Protegida (DOP) for wines located in the south of the province of Lugo and in the north of the province of Ourense, in Galicia, Spain. It extends over the territories of 20 different municipalities that conform a zone and entity called Ribeira Sacra, which could be translated as "Sacred Shore". The vineyards are planted on the steep slopes of the valleys and canyons of the rivers Miño and Sil. The area acquired official Denominación de Origen status in 1996.
