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.

This station is the nearest one to Lord's Cricket Ground and Abbey Road Studios.

It was opened November 20, 1939 on the Stanmore branch of the Bakerloo Line and was transferred to the Jubilee Line in 1979.

In recent years, the station has achieved a small amount of notoriety due to it being the only London Underground station that has no letters in common with the word 'mackerel', a fact that has frequently appeared in quizzes since the fact was inexplicably publicized. The word 'mackerel' is by no means unique in this feat, however, as several hundred words ('algebra', 'blackberry', 'paperclip'...) satisfy the same property of having letters in common with all stations except St John's Wood. Furthermore, St John's Wood is not unique in being able to satisfy such a restriction, and there are at least 84 stations for which words exist that have no letters in common with exactly one station (for example 'wavelength' & Oxford Circus; 'photocopying' & Russell Square).
