The Hatfield & St Albans Railway was a branch of the Great Northern Railway which connected St Albans to Hatfield in Hertfordshire, England. It opened in 1865 with the principal aim of allowing St Albans traffic to access the Great Northern's main line to London at , but soon came into difficulties when the Midland Railway inaugurated a direct route to London through St Albans. Passenger receipts declined in the 1930s, resulting in the temporary withdrawal of services in 1939. Passenger services were permanently withdrawn in 1951, leaving goods traffic to linger on until December 1968. Much of the route of the line is now incorporated into the Alban Way, a footpath and cycleway.
