雷德尼茨河（德语：Rednitz）位于德国巴伐利亚州境内，由两条河流汇合而成，流经罗特、施瓦巴赫和纽伦堡，最终在菲尔特与佩格尼茨河汇流形成雷格尼茨河。

The Rednitz is a 46 km long river in Franconia, Germany, tributary of the Regnitz (more precisely: its southern, left headstream). The Rednitz is formed by the confluence of the rivers Fränkische Rezat and Schwäbische Rezat, in Georgensgmünd (district of Roth). 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.
