The Reuss (Swiss German: Rüüss) is a river in Switzerland. With a length of 164 kilometres (102 mi) and a drainage basin of 3,426 square kilometres (1,323 sq mi), it is the fourth largest river in Switzerland (after the Rhine, Aare and Rhône). The upper Reuss forms the main valley of the canton of Uri. The course of the lower Reuss runs from Lake Lucerne to the confluence with the Aare at Brugg and Windisch.

The Gotthardreuss rises in the Gotthard massif, emerging from Lago di Lucendro (reservoir built in 1947; elevation 2,134 m) in the canton of Ticino and passing into the canton of Uri at Brüggboden (1,910 m). The Furkareuss rises east of Furka Pass from Schwärziseeli and forms the Urserental, passing Realp at 1,540 m.

Gotthardreuss and Furkareuss join at Hospental (1,452 m). Downstream of Andermatt (1,432 m) the Reuss passes through Schöllenen Gorge and under the legendary Devil's Bridge. At Göschenen (1,102 m) it is joined by the Göschenerreuss. From here it forms the main valley of the canton of Uri, passing below Wassen (840 m), Gurtnellen (711 m), Silenen (500 m), and through Erstfeld (471 m), past Attinghausen and Altdorf (452 m), joining the southernmost part of Lake Lucerne (the Urnersee) at Seedorf (434 m).
