Lupara (Italian pronunciation: [luˈpaːra]) is an Italian word used to refer to a sawed-off shotgun of the break-open type. It is traditionally associated with Cosa Nostra, the Italian organized crime group dominant in Sicily for their use of it in vendettas, defense — such as its use against Benito Mussolini's army when he decided to break up the Sicilian mafioso network—and hunting.

The shortened barrel (or barrels) of a lupara lend themselves to easier handling in wooded areas, or to easier concealment and indoor deployment in urban areas. The absence of choke and the shortened barrel contribute to a wider spread of shot than that of a choked full-length gun.
