N.V. Deli Spoorweg Maatschappij (DSM, lit. 'Deli Railway Company plc'), was a private railway company that operated near the east coast of Sumatra around Deli (now Medan). The Deli Company established itself as a tobacco plantation and then expanded into tea, rubber and timber products. The company was founded in 1883. Routes were built in 1,067 mm (3 ft 6 in) (cape gauge}. It was the last remaining private Dutch railway when it was taken over by the Indonesian State Railways in 1957.

All DSM lines are operated under the 1st Regional Division of Indonesian Railways.
