Duke of Carcaci () (pron: "Car-catch-ee") is a title in the Kingdom of Sicily, held by the head of one branch of the House of Paternò, a major Sicilian noble family.
The estate of Carcaci, from which the dukedom and the branch is named, is situated in Sicily, 20 miles north-west of Catania (where survives the ducal palazzo), at the junction of the River Simeto and River Salso. It is thus situated about 15 miles west of the crater of Mount Etna. The first Duke of Carcaci was Don Vincenzo Paternò Castello (1681âÂÂ1767) who in 1725 was created in Vienna a duke in the Kingdom of Sicily by Charles VI, Holy Roman Emperor and King of Sicily.
Carcaci had become the seat of a feudal barony shortly after the Norman Conquest of Sicily in 1061, when the first castle was built on the site. The barony and estate was acquired by this branch of the Paternò family in 1719.
