Diocese of Fossano
diocese of the Catholic Church in Italy

The Diocese of Fossano (Latin: Dioecesis Fossanensis) was a Latin diocese of the Catholic Church in Piedmont, in the Province of Cuneo. It was a suffragan of the Archdiocese of Turin.
Fossano became an episcopal see in 1592, through the reassignment of eleven localities from the diocese of Turin and four from the diocese of Asti. The diocese was suppressed in 1802 during the control of the French Consulate and the First Empire, and reestablished in 1817. In 2023, it was united with the Diocese of Cuneo to form the Diocese of Cuneo-Fossano.
History
The diocese of Fossano was established by Pope Clement VIII in a bull which he signed on 15 April 1592. On the same day he addressed a bull of appointment to Bishop Camillo Daddeo, transferring him to Fossano from the diocese of Brugnano. He also addressed a letter to the Archbishop of Turin, notifying him of the transfer of a number of parishes from his jurisdiction to that of the new diocese. He addressed another to the people of Fossano, notifying them of the promotion of their town (oppidum) to the status of a city (civitas). Finally, the Pope wrote to Charles Emmanuel I, Duke of Savoy, officially notifying him of the creation of the diocese and the appointment of Bishop Daddeo.

A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
