Italy is located in southern Europe.

The territory includes the mainland and the islands of Sardinia and Sicily as well as some other smaller islands. The country is predominantly mountainous with plains accounting for less than 33% of the land area. The two principal mountain ranges are (1.) the Alps which are divided into the three ranges of the Western Alps, the Central Alps and the Eastern Alps. (2.) The Apennines which is divided into the Northern or Ligurian Apennines and the Tuscan-Emilian Apennines. Except for the Po Plain, the plains of Italy are small in land area and numbers. The principal rivers are the Po, Tevere or Tiber, Arno, Volturno, Liri and Adige as well as many shorter rivers that flow to the Adriatic Sea.
