The Utrecht–Kampen railway is an important railway line in the Netherlands running from Utrecht to Kampen, passing through Bilthoven, Amersfoort, Nijkerk, Ermelo, Harderwijk, Nunspeet, Wezep and Zwolle. The line was opened between 1863 and 1865 by the Nederlandsche Centraal-Spoorweg-Maatschappij. Its northern part (Zwolle–Kampen) is known as the Kamperlijntje, currently operated by Keolis Nederland.
