The Roman Catholic diocese of Sansepolcro was a Latin rite see in Tuscany, central Italy.[1][2] It was erected in 1515, as the Diocese of (Borgo) Sansepolcro (Italian),[3] though difficulties prevented the appointment of a bishop until 1520.[4] On 30 September 1986, the diocese was suppressed and united with the Diocese of Arezzo and the Diocese of Cortona to form the Diocese of Arezzo-Cortona-Sansepolcro.
The diocese has always been a suffragan of the archbishop of Florence.[5]
