The Rench is a river in the district of Ortenau, Baden-Württemberg, Germany and a right-side tributary of the Rhine River. Its source is near Kniebis Mountain not far from Bad Griesbach in the Black Forest. It runs for 59 km before it discharges into the Rhine River near Rheinau/Lichtenau.
The Rench runs along the Rench Valley through Bad Peterstal, Oppenau, Lautenbach, Oberkirch and Renchen. In Oppenau the Lierbach discharges into the Rench.
Its upper part, the "Wildrench", is a worthy destination for hikers coming from the Schwarzwaldhochstraße or the Baden wine route.
