The Wutach is a river, 91 kilometres long, in the southeastern part of the Black Forest in the German state of Baden-Württemberg. It is a right-hand tributary of the Rhine. In its lower reaches it flows for about 6 kilometres along the border with the canton of Schaffhausen, Switzerland.

The name Wutach means "furious water", referring to the whitewater rapids in the gorge. Wut is recognisably cognate to a modern German word for anger; ach, which forms part of the names of many rivers in the region, comes from an old Celtic word for water, cognate with Latin aqua.

The river changes its name twice before it discharges into the High Rhine near Waldshut:

It rises in the Southern Black Forest as the Seebach in a highland hollow known as the Grüble, only a few metres below the summit of the Seebuck, a subpeak of the Black Forest's highest mountain, the Feldberg. Shortly thereafter it drops in three cascades through a height of 62 metres down the Feldsee Waterfall into the rocky cirque lake of the Feldsee. Heading east-northeast, the stream then follows the glacially formed Bärental valley through the municipality of Feldberg to Lake Titisee. During this stretch it is joined by the Sägenbach, which rises on the Baldenweger Buck on the Feldberg. More than 70% of the average water volume of both streams is siphoned off before their confluence and diverted to the Schluchseewerk hydropower station. As a result, at the Bärental Gauge above the just under 5-metre-high Seebach Waterfall, the Seebach only has a volumetric flow of 0.3 m³/s instead of its natural 0,8 m³/s. Below the little waterfall the Seebach enters a flat valley basin which has filled the silted-up, upper part of the Titisee since the last ice age. The stream now flows in wide meanders through the bogs of the nature reserve before reaching Lake Titisee.
