Montefiascone Cathedral or the Basilica of Santa Margherita (Italian: Duomo di Montefiascone; Basilica Cattedrale di Santa Margherita) is a former Roman Catholic cathedral in Montefiascone in the province of Viterbo, Italy, dedicated to Saint Margaret of Antioch, the patron saint of the town. It was formerly the episcopal seat of the Diocese of Montefiascone (suppressed and incorporated into the Diocese of Viterbo in 1986) and is now a basilica minor (status bestowed in 1943).
It is one of the most important churches in the area, and has one of the largest domes in Italy (27 m of diameter), which is visible from most of the towns of the Viterbo area.
