The Limmat is a river in Switzerland. The river commences at the outfall of Lake Zurich, in the southern part of the city of Zurich. From Zurich it flows in a northwesterly direction, after 35 km reaching the river Aare. The confluence is located north of the small town of Brugg and shortly after the mouth of the Reuss.

The main towns along the Limmat Valley downstream of Zurich are Dietikon, Wettingen, and Baden. Its main tributaries are the Linth, via Lake Zurich, the Sihl, in Zurich, and the Reppisch, in Dietikon.

The hydronym is first attested in the 8th century, as Lindimacus. It is of Gaulish origin, from *lindo- "lake" and *magos "plain", and was thus presumably in origin the name of the plain formed by the Linth.

Like many Swiss rivers, the Limmat is intensively used for production of hydroelectric power: along its course of 35 km (22 mi), its fall is used by no less than ten hydroelectric power stations. These include:

Historically, the Limmat was an important navigation route. In the twelfth and thirteenth centuries, voyages from Zurich to Koblenz are recorded. In 1447, the Emperor Frederick III granted the privilege of free navigation on the Limmat and on the Rhine to Zurich. Because of the current, navigation was typically downstream only, with the barges being sold on arrival.

Today, the Limmat is navigable for much of its length by small craft only, with many of the hydroelectric power plants incorporating boat lifts. The traditional boat type used on the river is the weidling, a flat-bottomed vessel that is usually 10 metres (33 ft) long.
