Helmdon Disused Railway is a 16.6-hectare (41-acre) linear biological Site of Special Scientific Interest between Helmdon and Brackley in Northamptonshire.[1][2]

This site is the former embankment and cutting of the Great Central Railway, which closed in 1966.[3] It is Jurassic grassland, and limestone spoil heaps have a very diverse floral community. Butterflies include the nationally scarce wood white and five nationally declining species. It is the only location in the county for the small blue butterfly.[4]

A public footpath runs along the site.[5]

The route of the HS2 High Speed railway crosses the southern end of the site.[6]
