Risch is a municipality in the canton of Zug in Switzerland. It is also promoted as Risch-Rotkreuz. Four villages (Rotkreuz, Risch, Buonas and Holzhäusern) belong to the municipality Risch. On 24 November 2007 it was decided to promote the municipality as Risch-Rotkreuz. The change was made because the village Rotkreuz has become much bigger than Risch.

The municipality is between the Lake of Zug and the river Reuss. In the south, the Rooterberg is a part of the municipality. Many little rivers and two little lakes flow in Risch-Rotkreuz. The municipality historically consists of the four villages of Risch, Buonas and Holzhäusern and Rotkreuz.
