Iglesia de Santa María (Valdediós) is a church in Villaviciosa, Asturias, Spain.

It is a late-Romanesque style Cistercian church[1] built in the 13th century.

The church is made up of three naves with semicircular apses and ribbed vaults.

The church is the only element that survives from the initial construction of the monastery, because the other buildings that made up the group deteriorated due to successive floods in the area.
