The Rednitz is a 46 km (29 mi) long river in Franconia, Germany, tributary of the Regnitz. Slightly richer in water than the other source river Pegnitz and also richer in tributaries, it is hydrographically regarded as the upper reaches of the Regnitz, although the longest flow path in its system is approx. 3 km shorter than that in the Pegnitz system. The Rednitz is formed by the confluence of the rivers Franconian Rezat and Swabian Rezat, in Georgensgmünd. The Rednitz flows north through Roth bei Nürnberg, Schwabach and the southwestern quarters of Nuremberg. The Rednitz joins the Pegnitz to form the Regnitz in Fürth.
