Location of some among the main Italian rivers
Location of some among the main Italian rivers

This is a list of rivers which are at least partially located in Italy. They are organized according to the body of water they drain into, with the exceptions of Sicily and Sardinia, which are listed separately. At the bottom, all of the rivers are also listed alphabetically.

Italian rivers are generally shorter than those of other European regions because Italy is partly a peninsula along which the Apennine chain rises, dividing the waters into two opposite sides. The longest Italian river is the Po, which flows for 652 km (405 mi) along the Po Valley.

Rivers in Italy total about 1,200,[1] and give rise, compared to other European countries, to a large number of marine mouths. This is due to the relative abundance of rain events in Italy, and to the presence of the Alpine chain rich in snowfields and glaciers in the northern part of the country, in the presence of the Apennines in the center-south and in the coastal extension of Italy.

For the purposes of this list, the Italian rivers draining into the Adriatic Sea begin at the coastal border between Italy and Slovenia and follow the Adriatic coast of Italy until it reaches Santa Maria di Leuca. Beyond this point, rivers empty into the Ionian Sea rather than the Adriatic. The rivers are ordered according to how far along the coast the river mouth is from the Italian/Slovenian border, the first river having its mouth the closest to the border and the last being closest to Santa Maria di Leuca.

For the purposes of this list, the Italian rivers draining into the Ligurian Sea begin at San Pietro Point near Portovenere in the east and extend to the border with France near Monaco. Sardinian rivers are excluded from this list because those rivers are in their own section below. The rivers are ordered according to how close their mouth is to San Pietro Point. The river with its mouth closest to this geographic point is listed first and rivers further away from this point are listed in the order in which their mouth empties into the sea as one proceeds along the coast up to the border with France.
