The Hollandsche IJzeren Spoorweg-Maatschappij (Dutch pronunciation: [ˈɦɔlɑntsə ˈɛizərə(n) ˈspoːrʋɛxmaːtsxɑˌpɛi]) or HSM (Hollands Iron Railway-Company) was the first railway company in the Netherlands founded on 8 August 1837 as a private company, starting operation in 1839 with a line between Amsterdam and Haarlem. The company remained operational until 1938, when it merged with the Maatschappij tot Exploitatie van Staatsspoorwegen (SS) to form the Nederlandse Spoorwegen (NS).
