The Reppisch is a river in Switzerland. It rises in the Türlersee and joins the Limmat as its tributary, near the town of Dietikon. The Reppisch flows in the Säuliamt (Affoltern district), canton of Zürich, an area featuring still partially untouched nature.
Between Birmensdorf and Dietikon, the river crosses a narrow valley which is used as a target range by the Swiss army troops stationed in the infantry barracks nearby. Therefore, this valley may be closed to entry during some parts of the week.
Shortly before entering Dietikon, the river underruns the Mutschellenpassstrasse and the Bremgarten-Dietikon-Bahn railway. In the spring of 1999, there were heavy floods in this area, blocking the road and the railway service for several days.
