Chigwell was a parliamentary constituency represented in the House of Commons of the Parliament of the United Kingdom from 1955 to 1974.
The seat was abolished by the Second Review for the February 1974 general election when the bulk of the electorate formed the basis of the new constituency of Epping Forest, together with parts of the abolished constituency of Epping.
The constituency consisted of the Urban District of Chigwell (transferred from Woodford) and the Rural District of Ongar (transferred from Chelmsford).
[1] On abolition, Chigwell, which comprised the bulk of the constituency, was included in the new constituency of Epping Forest and the Rural District of Ongar (now part of the merged Rural District of Epping and Ongar) was included in the new constituency of Brentwood and Ongar.
A small part in the south (part of Hainault) had been absorbed into the London Borough of Redbridge on its creation within Greater London and was now added to Ilford North.
