The Piave (Italian: [ˈpjaːve]; Latin: Plavis) is a river in Northeast Italy. It begins in the Alps and flows southeast for 220 kilometres (140 mi) into the Adriatic Sea near the city of Venice. One of its tributaries is the Boite.
In 1809 it was the scene of a battle during the Napoleonic Wars, in which Franco-Italian and Austrian forces clashed.

Veneto, officially the Region of Veneto, is one of the 20 regions of Italy, located in the north-east of the country. It is the 4th most populous region in Italy, with a population of 4,851,851 as of 2025. Venice is the region's capital while Verona is the largest city.
Veneto was part of the Roman Empire until the 5th century AD. Later, after a feudal period, it was part of the Republic of Venice until 1797. Venice ruled for centuries over one of the largest and richest maritime republics and trade empires in the world. After the Napoleonic Wars and the Congress of Vienna, the former Republic was combined with Lombardy and re-annexed to the Austrian Empire as the Kingdom of Lombardy–Venetia, until that was merged with the Kingdom of Italy in 1866, as a result of the Third Italian War of Independence and of a plebiscite.
The Po Valley, Po Plain, Plain of the Po, or Padan Plain (Italian: Pianura Padana, pronounced [pjaˈnuːra paˈdaːna], or Val Padana) is a major geographical feature of northern Italy. It extends approximately 650 km (400 mi) in an east-west direction, with an area of 46,000 km (18,000 square miles) including its Venetic extension not actually related to the Po basin; it runs from the Western Alps to the Adriatic Sea. The flatlands of Veneto and Friuli are often considered apart since they do not drain into the Po, but they effectively combine into an unbroken plain, making it the largest in Southern Europe. It has a population of 17 million, or a third of Italy's total population.
The plain is the surface of an in-filled system of ancient canyons (the "Apennine Foredeep") extending from the Apennines in the south to the Alps in the north, including the northern Adriatic. In addition to the Po and its affluents, the contemporary surface may be considered to include the Savio, Lamone and Reno to the south, and the Adige, Brenta, Piave and Tagliamento of the Venetian Plain to the north, among the many streams that empty into the north Adriatic from the west and north.
The Boite (Cadorino dialect, Guóite) is a river of the Province of Belluno, Veneto region, northern Italy. Passing through the town of Cortina d'Ampezzo, it joins the Piave at Perarolo di Cadore. The principal valley, that of the Piave, runs parallel to the mountain chain which separates the province of Belluno from the basin of the Adige. The secondary valleys, which complete the river basin, are, in descending order and on the right bank, those of Visdende, Comelico Superiore, Auronzo, Boite and Zoldo, traversed, respectively, by the Silvella, or first branch of the Piave, the Padola, Ansiei, Boite, and Mae, which all flow into the main river in a rectangular direction.
The Battle of Piave River was fought on 8 May 1809 between the Franco-Italian army under the command of Eugène de Beauharnais and an Austrian army led by Archduke John of Austria. The Austrian commander made a stand behind the Piave River but he suffered a defeat at the hands of his numerically superior foes. The combat took place near Nervesa della Battaglia, Italy during the War of the Fifth Coalition, part of the Napoleonic Wars.
The initial Austrian invasion of Venetia succeeded in driving the Franco-Italian defenders back to Verona. At the beginning of May, news of Austrian defeats in Bavaria and inferiority in numbers caused Archduke John to begin retreating to the northeast. When he heard that his enemies were crossing the Piave, the Austrian commander turned back to give battle, intending to slow Eugène's pursuit of his army.
The Botteniga is a river in northern Italy. It is a distributary of the Piave, and meets the Sile at Treviso after descending approximately 60 metres over its 20 kilometre course.
