The Wolverton–Newport Pagnell line was a railway branch line in Buckinghamshire, United Kingdom running from Wolverton on the London and North Western Railway (LNWR) (today's West Coast Main Line) to Newport Pagnell. The line fully opened to passengers in 1867. An extension to Olney was planned in 1865, but this scheme was abandoned after partial construction. Earthworks along the route of the extension still exist in Bury Field (Newport Pagnell), and plaques exist detailing the history of the failed project.
