List of rivers of Italy
Introduction Location of some among the main Italian riversThis 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  along the Po Valley.Rivers in Italy total about 1,200, 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.
Characteristics of Italian rivers Flamingos in the delta of the Po river* The widest and largest rivers belong to the Alpine region due to the arrangement and elevation of the relief, as well as the depth of the Po Valley. * Along the peninsula, given the arrangement of the Apennine chain and the different slopes of the two sides, the rivers on the Adriatic and Ionian sides run through short transversal valleys and, except for the Reno, do not exceed  in length, while ten are just over . On the Tyrrhenian side instead, they are on average longer because the Apennine spurs and the sub-Apennine belt are wider. * The rivers that flow into the Tyrrhenian sea are longer also because for the first stretch, they follow longitudinal valleys (Apennine valleys) and then run transversally with respect to the axis of the chain, in the south-Apennine area. * Given the location of the springs and the local rainfall regime, the rivers of Italy are divided into:**Alpine rivers, of glacial origin, subject to flooding in spring and summer because when it is hot the glaciers melt. The lakes that frequently occupy the most depressed parts of the Alpine valleys serve to dampen the rush of the rivers and to clarify their murky waters. In fact, given the rapidity of the valleys from which the rivers descend, the speed of their waters is remarkable and their activity of erosion and transport of rocky debris is sensitive. Decanting is precisely the process by which this material is abandoned in the lakes of which these rivers are tributaries. **Apennine rivers, subject to sudden spring and autumn floods due to the rains. The lean period is in summer accentuated in the Northern Apennines, almost absolute in the southern one, except for some waterways (Aterno-Pescara, Sele, Volturno, Liri-Garigliano, to be limited to those that flow directly into the sea, to which are added Velino, Nera, Aniene all in the Tiber basin, etc.) which are fed by large karst springs that spring on the edge of areas characterized by permeable fissured rocks. In fact, there are no snowfields and glaciers on the Apennines (the only glacier, albeit small, is that of the Calderone, on the northern side of Corno Grande, in the Gran Sasso d'Italia massif, in Abruzzo); rainwater does not always collect in river beds made up of impermeable ground, that is, such as to allow a fair average annual flow. **The Sardinian and Sicilian rivers are torrential (full of water in winter and almost dry in summer), with the exception of Tirso, Flumendosa, Coghinas and Simeto.

Draining into the [[North Sea]] *Reno di LeiFrom the artificial Lago di Lei (the barrage itself is part of Switzerland), the Reno di Lei runs for a few kilometers through northern Italy before entering Switzerland again, and drains via the Reno di Avers and the Hinterrhein into the Rhine.
Draining into the [[Black Sea]] Acqua Granda (or Spöl)*Drava (a short section in Italy, continues into Austria, Slovenia, Croatia and Hungary)The Drava drains into the Danube on the Croatia–Serbia border. **Slizza (three-quarters in Italy, a quarter in Austria)After entering Austria, the Slizza drains via the Gail into the Drava. *Acqua Granda (half in Italy, half in Switzerland)After entering Switzerland, the Spöl drains into the Inn, which meets the Danube in Germany.
Draining into the [[Adriatic Sea]] Reno near CasalecchioFor 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. *Timavo (Reka)*Isonzo (Soča)**Vipacco (Vipava)**Torre***Natisone*Cormor*Ausa*Tagliamento*Livenza*Piave*Brenta*Bacchiglione*Adige*Tartaro-Canalbianco-Po di Levante*Po*Reno**Senio**Santerno**Sillaro**Idice***Savena**Samoggia**Limentra di Sambuca**Limentra orientale*Lamone*Uniti**Bidente-Ronco**Montone***Acquacheta***Rabbi*Savio*Rubicon*Marecchia**San Marino*Ausa*Marano*Conca*Foglia*Metauro**Candigliano***Biscubio***Burano*Cesano*Misa**Nevola*Musone*Potenza*Chienti**Fiastrone**Fiastra*Tenna*Aso*Tesino*Tronto**Castellano*Salinello*Tordino*Vomano**Fucino**Mavone*Piomba*Saline**Fino**Tavo*Aterno-Pescara**Sagittario***Gizio*Alento*Foro*Moro*Sangro*Trigno*Biferno*Fortore*Carapelle**Calaggio**Carapellotto*Ofanto**Locone*Canale Reale===Tributaries of the Adige===The Adige crossing Verona. *Avisio*Eisack**Braibach**Derjon**Eggentaler Bach**Pfitscher Bach**Pflerscher Bach**Plima**Ridnauner Bach**Rienz***Ahr****Reinbach***Antholzer Bach***Gran Ega***Gsieser Bach***Pragser Bach***Pfunderer Bach**Talfer**Villnößer Bach*Karlinbach*Passer*Rom*Saldurbach*Schnalser Bach*Suldenbach*Falschauer===Tributaries of the Po===Po in Boretto (RE).The tributaries of the Po are organized into right- and left-hand tributaries.
