The Basque Museum, with the original name of the Basque Archaeological, Ethnographic and Historical Museum, is a museum in Bilbao, Spain. It opened its doors in 1921, occupying the ground floor of the baroque cloister of the old Colegio de San Andrés, which belonged to the Jesuits until their expulsion from Spain in 1767; the adjacent church of Santos Juanes, today a regular worship parish, is the church that once belonged to the Jesuit college.
