Mornington Crescent is a London Underground station in Camden Town in north west London, named after the nearby street. The station is on the Charing Cross branch of the Northern line, between Euston and Camden Town. It is in Travelcard Zone 2.
The station was opened as part of the original route of the Charing Cross, Euston & Hampstead Railway (now the Charing Cross branch of the Northern line) on 22 June 1907. Prior to the station's opening, the name of "Seymour Street" had been proposed. After opening, it was little used, and for many years it was open only on weekdays, and before 1966 Edgware-bound trains passed through without stopping.
