St John's Wood tube station is a London Underground station at St John's Wood. It is on the Jubilee Line, between Swiss Cottage and Baker Street. It is in Travelcard Zone 2.

The station was opened on 20 November 1939 on a new section of deep-level tunnel constructed between Baker Street and Finchley Road when the Metropolitan Line's services on its Stanmore branch were transferred to the Bakerloo Line.

With the opening of St John's Wood station, two nearby stations on the Metropolitan Line were closed. These were Lord's (which had originally been opened in 1868 as St John's Wood Road) and Marlborough Road.
