The Vienne (French pronunciation: [vjɛn] ⓘ; Occitan: Vinhana, pronounced [viɲaˈno]) is a major river in south-western France.

It supports numerous hydroelectric dams, and it is the main river of the northern part of the Nouvelle-Aquitaine region.

The Vienne rises as a spring in the department of Corrèze, at the foot of Mont Audouze, on the Plateau de Millevaches, near Peyrelevade.

En route to its confluence with the Loire, the Vienne is joined by the rivers Creuse and Clain.

Finally, after a journey of 372 km it reaches the Loire at Candes-Saint-Martin in the department of Indre-et-Loire.
