The Cathedral of Saint Peter, Saint Paul, and Saint Andrew of Saint-Claude (French: Cathédrale Saint-Pierre, Saint-Paul et Saint-André de Saint-Claude), commonly known as Saint-Claude Cathedral, is a Roman Catholic cathedral and a national monument of France, located in the town of Saint-Claude.
The present cathedral was previously the church of the former Condat Abbey (founded in the 5th century), which with the village that grew up round it soon acquired however the name of Saint-Oyand or Saint-Oyend after Saint Eugendus (d. 510), fourth abbot and a popular saint. In 687 Saint Claudius resigned as Bishop of Besançon and became the twelfth abbot. After he died, in 696, his grave became a very popular pilgrimage centre, to the extent that by the thirteenth century, the name "Saint-Claude" had become more used than that of "Saint-Oyand", which it superseded.
The Bishopric of Saint-Claude was created in 1742, out of the parishes in the care of the abbey. The abbey church, built in the 15th century, became the cathedral.
