The Rhine-Ruhr S-Bahn (German: S-Bahn Rhein-Ruhr) is a polycentric S-bahn network covering the Rhine-Ruhr Metropolitan Region in the German federated state of North Rhine-Westphalia. This includes most of the Ruhr (and cities such as Dortmund, Duisburg and Essen), the Berg cities of Wuppertal and Solingen and parts of the Rhineland (with cities such as Cologne and Düsseldorf). The easternmost city within the S-Bahn Rhine-Ruhr network is Unna, the westernmost city served is Mönchengladbach.

The S-Bahn operates in the areas of the Verkehrsverbund Rhein-Ruhr and Verkehrsverbund Rhein-Sieg tariff associations, touching areas of the Aachener Verkehrsverbund (AVV) at Düren and Westfalentarif at Unna. The network was established in 1967 with a line connecting Ratingen Ost to Düsseldorf-Garath.

The system consists of 16 lines. With a system length of 676 km (420.05 mi), it is the second-largest S-Bahn network in Germany, behind S-Bahn Mitteldeutschland. Most of them are operated by DB Regio NRW, while line S28 is operated by Regiobahn and S7 by RheinRuhrBahn. S28 and S7 are two non-electrified lines of the network. The S19 will run 24/7 between Düren and Hennef for 17 stations and not only between Cologne Hbf and Cologne/Bonn Airport.
