Dortmund Hauptbahnhof is the main railway station in Dortmund, North Rhine-Westphalia, Germany. The station's origins lie in a joint station of the Köln-Mindener Eisenbahn and Bergisch-Märkische Eisenbahn which was built north of the city centre in 1847. That station was replaced by a new station, erected in 1910 at the current site. It featured raised embankments to allow a better flow of traffic. At the time of its opening, it was one of the largest stations in Germany. It was, however, destroyed in an Allied air raid on 6 October 1944.

Dortmund is the third-largest city in North Rhine-Westphalia, after Cologne and Düsseldorf, and the ninth-largest city in Germany. With a population of 612,065 inhabitants, it is the largest city of the Ruhr as well as the largest city of Westphalia. It lies on the Emscher and Ruhr rivers in the Rhine-Ruhr Metropolitan Region, the second biggest metropolitan region by GDP in the European Union, and is considered the administrative, commercial, and cultural centre of the eastern Ruhr. Dortmund is the second-largest city in the Low German dialect area, after Hamburg.
