Saint-Dié Cathedral (French: Cathédrale Saint-Dié de Saint-Dié-des-Vosges) is a Roman Catholic church and monument historique of France, located in the town of Saint-Dié-des-Vosges in Lorraine.
Deodatus of Nevers, the eponymous Saint Dié,[1] founded a monastery here in the 7th century and gave up his episcopal functions to retire to this place.
Among those who subsequently held the rank of provost or dean were Giovanni de Medici, afterwards Pope Leo X, and several princes of the ducal House of Lorraine.
Though they co-operated in building the town walls, the canons and the dukes of Lorraine soon became rivals for authority over the town of Saint-Dié, where towards the end of the 15th century one of the earliest printing presses of Lorraine was founded.
The institution of a town council in 1628, and the establishment in 1777 of the bishopric which appropriated part of their spiritual jurisdiction, contributed greatly to diminish the influence of the canons; and with the French Revolution they were completely swept away.
