Northwick Park is a London Underground station in Kenton in the London Borough of Brent on the Metropolitan line. It lies between Harrow-on-the-Hill and Preston Road stations and is in Travelcard zone 4. The station takes its name from the nearby public park, Northwick Park.

Kenton is a district in north-west London, England, to the east of Harrow and historically in Middlesex. As with surroundings in Harrow, Wembley and Kingsbury, the area was a product of Metroland suburbia of the early 20th century. Both the London and North Western Railway and Metropolitan Railway reached the area by the 1920s. The main road through Kenton, the east-west Kenton Road, is a busy and important road that links Harrow to the major Edgware Road. The road now forms the boundary between the London boroughs of Harrow and Brent.
