Clapham North tube station is an Underground station in Clapham, London. It is on the Northern line between Clapham Common and Stockwell. The station is located in Travelcard Zone 2, at the northern end of Clapham High Street, and a short walk away from Clapham High Street railway station. Although there is no direct interchange link interchange between the two it is counted as an Out of Station Interchange on Oyster, so journeys involving a change between the two are charged as through journeys and not two separate journeys.
The station opened as Clapham Road on 3 June 1900 as part of an extension of the City & South London Railway to Clapham Common one stop to the south. The station, designed by TP Figgis, is one of two remaining stations that has an island platform in the station tunnel, serving both the northbound and southbound lines; the other is Clapham Common. The original station building was replaced in the mid-1920s when the line was modernised and the original building was remodelled by Charles Holden. The ticket hall was rebuilt after the installation of escalators and Figgis's station facade was replaced with biscuit-cream faience slabs and black coping tiles to the parapet walls. In turn the station has recently had its façade reclad. The station's name was changed to Clapham North on 13 September 1926 after the line was extended to Morden that year.
Clapham North is one of eight London Underground stations which has a deep-level air-raid shelter beneath it.
London Buses routes 50; 88; 155; 322; 345; P5 and night route N155 serve the station.
