The Diocese of Tuscanella (Latin: Tuscaniensis) was a Latin Church residential bishopric of the Catholic Church, in existence by the 7th century.Kehr, Italia pontificia II, p. 196: "Quod autem ad Tuscaniam attinet, certe iam saec. VII sedes episcopalis...." Even at the time of the Lombard invasions, it belonged to the Duchy of Rome and was immediately subject to the Pope.Louis Duchesne, "Les évêchés d'Italie et l'invasion lombarde," Mélanges d'archéologie et d'histoire 23 (Paris: Fontemoing 1903), pp. 89-90. The seat of the bishop was originally in the church of S. Maria, then in the church of S. Pietro, and after 1592 in the church of S. Giacomo.Kehr, p. 196.

On 22 February 852 Pope Leo IV, in the bull Convenit apostolico, addressed to Bishop Virbono, confirmed the jurisdiction of the bishop over the churches and possessions of his diocese.Campanari, I, pp. 114-115; II, pp. 92-108. This document is revealing, because it not only describes the towns and parishes dependent on the bishop (including Montalto, Tarquinia and Viterbo), but also details the boundaries of the diocese.Cappelletti, pp. 80-87. Signorelli, Viterbo nella storia, pp. 68-78 (dating the bull to 850 rather than 852.

From 1192 the diocese of Tuscanella and the diocese of Viterbo were in personal union (aeque principaliter).Paul Fridolin Kehr points out that Cardinal Joannes of S. Clemente signs himself "Tuscanensis episcopus" until August 1192, and then from 4 October 1192 signs himself "Viterbiensis et Tuscanensis episcopus. Kehr, Italia pontificia II, p. 208.

The diocese was suppressed in 1986.

The name, though not the diocesan structure, was revived as the Latin Catholic titular see of Tuscania in 1991.David M. Cheney.Catholic-Hierarchy.org.
