List of Parliamentary constituencies in Essex
The county of Essex (which includes the unitary authorities of Southend-on-Sea and Thurrock) is divided into 18 Parliamentary constituencies (sub-classified into six of borough type and twelve of county status affecting the level of expenses permitted and status of returning officer). The county in common with Surrey saw the vast bulk of its population and seats removed on the creation of the County of London in 1887 combined with its wider replacement the county of Greater London in 1965. Reflecting the present definition of the rump county, all of Essex's seats were won by Conservative MPs at the United Kingdom General Election, 2017. Conservatives have won a majority of the Essex seats since the removal of large, heavily populated parts of the county into Greater London in 1965.

Following the 2017 General Election, the Conservative Party made a net gain of one seat in Essex by gaining the seat of Clacton from UKIP. This also saw Thurrock become the most marginal seat in the county. 2017 was the first time since 1987 that Essex had returned a full slate of Conservative MPs.

Changes proposed in 2016
As part of the Sixth Periodic Review of Westminster constituencies the Boundary Commission for England proposed the following constituencies for Essex at the 2020 general election.
Changes of substance are tabularised in summary of results below since the division of the two-member seat of Essex. One change of name has occurred during the currency of a seat's borders, that is, other than on boundary reviews — Woodford (almost all of which seat is no longer in the county) was renamed in 1964 to become Wanstead and Woodford and at least three such changes since 1965, see tables in the summary of results section below.
