Brentwood is a town, the principal settlement of the Brentwood (borough), part of Essex in England. It is located in the London commuter belt, 20 miles (30 km) east north-east of Charing Cross in London and near the M25 motorway.
Brentwood is an affluent suburban town with a small, but expanding, shopping area and high street. Beyond this is extensive sprawling residential development entirely surrounded by open countryside and woodland; some penetrating to within only a few hundred yards of the town centre. It is perhaps most widely known for Brentwood School (Essex) and for several businesses based in the town.
