High Barnet or Chipping Barnet is a place in the London Borough of Barnet in Greater London, England. It lay on the border of the traditional counties of Hertfordshire and Middlesex.
The town lies at the northern end of the Northern Line, and the association football team Barnet F.C play there. It was formerly the site of a well-known fair, hence the cockney rhyming slang "Barnet" for "hair".
