The Lower Rhine region or Niederrhein is a region around the Lower Rhine section of the river Rhine in North Rhine-Westphalia, Germany, between approximately Oberhausen and Krefeld in the East and the Dutch border around Kleve in the West. As the region can be defined either geographically, linguistically, culturally, or by political, economic and traffic relations throughout the centuries, as well as by more recent political subdivisions, its precise borders are disputable and occasionally may be seen as extending beyond the Dutch border.
