Harrogate Gasworks Railway was an industrial railway in the town of Harrogate, North Yorkshire, England. It was built to the gauge of 2 ft and ran between Bilton Junction on the North Eastern Railway, to the Harrogate Gas Company's (HGC) works at New Park, north of the town centre. It opened in 1908 to carry coal to the works for gasification, and outbound byproduct liquids. It closed to traffic in 1956. The railway was noted for its tight gauge restrictions in the tunnel at New Park. Two of its steam locomotives have survived into preservation, and are still in use on heritage railways.

Bilton is a suburb of Harrogate, North Yorkshire, England, situated to the north-east of the town centre.
