Enfield was a constituency for the House of Commons of the UK Parliament from 1885 until 1950. The area sloping to the River Lea in the east was in the far north of Middlesex centred on the town of Enfield. The area formed part of the London conurbation and was much reduced over the course of its existence, in 1918 and then insignificantly in 1945 due to suburbanisation and urbanisation. It returned one Member of Parliament (MP).
