Roman Catholic Diocese of Cavaillon

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. 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 (NĂ´tre 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.

After the Concordat of 1801, the territory of the diocese passed to the diocese of Avignon.
