A rione (Italian pronunciation: [riˈoːne]; plural: rioni) is a neighbourhood in several Italian cities. A rione is a territorial subdivision. The larger administrative subdivisions in Rome are the municipi, with the rioni being used only in the historic centre. The word derives from the Latin regiones, the 14 subdivisions of Rome imposed by Augustus. The term has been adopted as a synonym of quartiere in the Italian comuni.
