Sudbury (/ˈsʌdbri/) is a suburb in the London Boroughs of Brent and Harrow, located in northwest London, United Kingdom. Sudbury is an historical area having once extended from the 'South Manor- Sudbury' (thought to have been on Harrow Hill) to the area that is now known as Wembley Central. Much of the land that once formed Sudbury Common until the 1930s has now been developed as a relatively green residential suburb of London. Much of Sudbury was once in the ownership of the Barham family who give their name to a number of local landmarks including Barham School and Barham Park.
