Edgware railway station was a London and North Eastern Railway (LNER) station in Station Road, Edgware, Greater London. It is not to be confused with the London Underground Northern line Edgware Station approximately 200 metres to the north east.
The station was built as the northern terminus of the Edgware, Highgate and London Railway (E&HLR) and was opened on 22 August 1867 by the Great Northern Railway (GNR) (which had taken over the EH&LR) in what was then rural Middlesex. The line ran from Finsbury Park to Edgware via Highgate with branches to Alexandra Palace and High Barnet. The previous station on the line was Mill Hill (The Hale).
Edgware railway station and the tracks to Mill Hill East continued to be used for goods services until 1964 when it was completely closed. Today, the track has been removed and the platforms and station buildings have been demolished. The site of Edgware railway station is now occupied by a shopping centre, alongside part of whose car park runs a small stretch of the former trackbed, leading to the still-standing bridge over the Northern line tracks into Edgware Underground station.
