The Haltern–Venlo railway is now largely disused and dismantled line in the German state of North Rhine-Westphalia and the Netherlands. It was opened in 1874 by the Cologne-Minden Railway Company (German: Cöln-Mindener Eisenbahn-Gesellschaft, CME) as part of the Hamburg-Venlo railway from Venlo in the Netherlands to a junction at Haltern am See on the Wanne-Eickel–Hamburg railway, which had been opened by the CME from Wanne to Munster in 1870. In contrast to the eastern section of the line, the Haltern-Venlo section ran at a loss from the beginning.
