The Gravesend West Line was a short railway line in Kent that branched off the Swanley to Chatham line at Fawkham Junction and continued for a distance of 5 miles (8 km) to Gravesend where the railway company constructed a pier to connect trains with steamers. It was opened in 1886 and closed to passenger services in 1953, remaining open to freight until 1968 before reopening briefly between 1972 and 1976. Part of the railway's former alignment was incorporated into the Channel Tunnel Rail Link.
Authorisation to construct the Gravesend West Line was obtained by the Gravesend Railway Company in the shape of the Gravesend Railway Act 1881 (c.cxliv) which received royal assent on 18 July 1881. The Act envisaged a junction with the Chatham Main Line near the village of Pinden which lies between the larger settlements of Farningham and Fawkham from which a line would run to Gravesend, a town already well-served by the railway. The project was driven by Sir Sydney Hedley Waterlow, Bart., the Liberal Member of Parliament for Gravesend and Deputy Chairman of the London, Chatham and Dover Railway (LCDR) which had built the Chatham Main Line. The LCDR's great rival, the South Eastern Railway (SER), attempted to block the scheme by seeking parliamentary authorisation for a loop line towards Northfleet and Snodland which would take in land required by the Gravesend Railway. The latter successfully petitioned against the SER's bill and obtained approval for its own scheme.
