South Italy

South Italy (Italia meridionale or Sud Italia) is one of the five official statistical regions of Italy used by the National Institute of Statistics (ISTAT), a first level NUTS region and a European Parliament constituency. South Italy encompasses six of the country's 20 regions:


 * Abruzzo
 * Apulia
 * Basilicata
 * Calabria
 * Campania
 * Molise

South Italy is defined only for statistical and electoral purposes. It should not be confused with the Mezzogiorno, or southern Italy, which refers to the areas of the former Kingdom of the Two Sicilies (once including the southern half of the Italian peninsula and Sicily) with the usual addition of the Western Mediterranean island of Sardinia. The latter and Sicily form a distinct statistical region, called Insular Italy.

South Italy borders central Italy to the northwest, while it is washed by the Adriatic Sea to the northeast, the Ionian Sea to the southeast and the Tyrrhenian Sea to the southwest.

It is crossed from north to south by the Apennine Mountains, whose highest mountain is the Gran Sasso d'Italia (2,912 m).
