Northwood Hills is a London Underground station in Northwood, north-west London. It is on the Metropolitan line, between Northwood and Pinner stations. It is in London fare zone 6.
The station opened on 13 November 1933. There was a competition for the name and Northwood Hills, suggested by a woman from North Harrow was the winning entry. The area is lower than Northwood, despite the name.
In the northbound direction, the station is served by trains to Watford (4tph), Amersham (2tph) and Chesham (2tph) trains (at peak times, 'fast' trains do not stop at stations between Harrow-on-the-Hill and Moor Park). In the southbound direction, off-peak services generally run 2tph to Wembley Park, 4tph to Baker Street, and 4tph to Aldgate.
London Buses routes 282, H11 (alighting at Northwood Hills Circus) and H13 serve the station.
