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, continuing a further 35 km until it reaches 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, Wägitaler Aa and Jona, all 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" (Welsh llyn) and *magos "plain" (Welsh maes), and was thus presumably in origin the name of the plain formed by the Linth.
