The Church of Saint Mary of Eunate is a 12th-century Catholic church of Romanesque construction located about 2 km south-east of Muruzábal, Navarre, Spain, on the Way of Saint James. Its origins are disputed due to lack of documentation. Its octagonal plan and the fact that it is not located in a present-day village or town but in the countryside contribute to its enigmatic nature. It is a site on the French Way path of the Camino de Santiago.
