De Arend (Dutch pronunciation: [də ˈʔaːrənt]; the eagle) was one of the two first steam locomotives in the Netherlands. It was a 2-2-2 Patentee type built in England by R. B. Longridge and Company of Bedlington, Northumberland to run on the then standard Dutch track gauge of 1,945 mm (6 ft 4+9⁄16 in). On 20 September 1839, together with the Snelheid (Dutch for speed), it hauled the first train of the Hollandsche IJzeren Spoorweg-Maatschappij between Amsterdam and Haarlem. It was withdrawn in 1857.

In 1939 a replica of the De Arend was constructed for the 100th anniversary of the Dutch railways. It is displayed at the Nederlands Spoorwegmuseum (Dutch Railway Museum) in Utrecht.
