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.

Kirkby-in-Ashfield is a market town in the Ashfield District of Nottinghamshire, England. With a population of 25,265, it is a part of the wider Mansfield Urban Area. The Head Offices of Ashfield District Council are located on Urban Road in the town centre.
