The Cologne-Minden Railway Company (German, old spelling: Cöln-Mindener Eisenbahn-Gesellschaft, CME) was along with the Bergisch-Märkische Railway Company and the Rhenish Railway Company one of the railway companies that in the mid-19th century built the first railways in the Ruhr and large parts of today's North Rhine-Westphalia.
