The Roman Catholic Diocese of Castro del Lazio was a residential bishopric from 600 to 1649 and is now a Latin Catholic titular see under the shortened name Castro.
The bishopric was founded in 600 AD under the name Bisenzio (and Latin Bisentium), the Italianized medieval name of the Ancient Etruscan city Visentium.
In 680 it was renamed as Diocese of Castro del Lazio, also called Castrum in Tuscia.
On 31 August 1369, it lost territory to establish the Roman Catholic Diocese of Montefiascone.
On 13 September 1649, it was suppressed and its territory used to establish the Roman Catholic Diocese of Acquapendente.
