Kennington tube station is a London Underground station in Kennington, on both the Charing Cross and Bank branches of the Northern Line. Its neighbours to the north are Waterloo on the Charing Cross branch and Elephant & Castle on the Bank branch; the next station to the south is Oval. It is in Travelcard Zone 2.

The junction between the two branches is immediately south of the station. As the route to the south has a limited capacity many trains terminate at Kennington; because of the layout of the reversing facilities it is almost always Charing Cross trains that do so. One of the station's four platforms is thus mainly used by terminating trains and sees relatively few departures.

The station was opened on December 18, 1890 as part of London's first deep-level tube, the City & South London Railway (now the Bank branch). Two extra platforms were added in 1926 when the connection to the Hampstead Tube (now the Charing Cross branch) was built. At this time the old northbound platform was reconstructed with the track running down the other side of the tunnel (to allow cross-platform interchange), resulting in unusually wide tunnel mouths.
