The former French diocese of Cavaillon (Lat. dioecesis Caballicensis) existed until the French Revolution as a diocese of the Comtat Venaissin, a fief of the Church of Rome. It was a member of the ecclesiastical province headed by the Metropolitan Archbishop of Avignon.[1] Its seat was at Cavaillon, in the south-eastern part of what is now France, in the modern department of Vaucluse.
The cathedral was officially dedicated to the Blessed Virgin Mary (Nôtre Dame), but popularly honored Saint Veranus, the sixth-century bishop of Cavaillon. In 1202 the cathedral had a Chapter composed of a Provost, a Precentor, and a Sacristan, to which were added the Archdeacon and 12 Canons.[2]
After the Concordat of 1801, the territory of the diocese passed to the diocese of Avignon.[3]
