Hendon is a place in the London Borough of Barnet. It is a suburban development situated 7 miles (11.3 km) north west of Charing Cross.

Hendon was historically a civil parish in the county of Middlesex. The manor is described in Domesday (1087), but the name, 'Hendun' meaning 'at the high hill', is earlier. There is even evidence of Roman settlement discovered by the Hendon and District Archaeological Society and others; an urn burial of a child was found in nearby Sunny Gardens Road. The Midland Railway and the Great Northern Railways came in the 1860s, and the underground, at Golders Green at least, in 1907. Much of the area developed into a suburb of London and now the area is mostly town with some countryside in the Mill Hill, and Edgware area. Hendon industry was mostly centred on manufacturing, and included motor and aviation works, and developed from the 1880s. In 1931 the civil parish of Edgware was abolished and its area was added to the civil parish of Hendon.

Hendon became an urban district in 1894. In 1932 the urban district became the Municipal Borough of Hendon. The municipal borough was abolished in 1965 and the area became part of the London Borough of Barnet.

Hendon’s claim to fame is in flying and Hendon Aerodrome is now the RAF Museum. The area is closely associated with the aviator Claude Grahame-White. Another part of the Aerodrome site is the Hendon Police College, the training centre for the Metropolitan Police.

It is a former borough and ancient parish. The name means the high place or down, and Hendon's motto is Endeavour. The Burroughs is a civic centre for the London Borough of Barnet, and also the site of Middlesex University Business School.
