Roman Catholic Diocese of Cavaillon
The former French diocese of Cavaillon 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.
