The Diocese of Sion (Latin: Dioecesis Sedunensis, French: Diocèse de Sion, German: Bistum Sitten) is a Latin Catholic ecclesiastical territory in the canton of Valais, Switzerland. It is the oldest bishopric in the country and one of the oldest north of the Alps. The history of the Bishops of Sion, of the Abbey of St. Maurice of Valais as a whole are inextricably intertwined.
