The Mansfield Railway was an eleven-mile railway line in Nottinghamshire, England. It was built to serve collieries opening in the coalfield around Mansfield, and ran between junctions at Clipstone and Kirkby-in-Ashfield on the Great Central Railway. It opened in 1916 and was worked by the GCR. Passenger stations were opened on the line, although, at the date of opening, road bus competition was already dominant.
The passenger service was withdrawn in 1956 and the line closed in stages as collieries ceased work, completely ending operation in 2003.
