Castro was an ancient city, believed to have been originally founded by the Latins, on the west side of Lake Bolsena in present-day Italy. It was subject of the Wars of Castro fought between Popes Urban VIII and Innocent X, and the Farnese Dukes of Parma — first Odoardo Farnese and then his son Ranuccio II. The wars ended badly for the city; on the orders of Pope Innocent X, the city was razed on September 2, 1649, and never rebuilt.

Castro is a comune (municipality) in the Province of Bergamo in the Italian region Lombardy, located about 80 km northeast of Milan and about 35 km northeast of Bergamo.
