List of parliamentary constituencies in Cleveland

Cleveland was abolished in 1996 both as a county council and a non-metropolitan county, but the name Cleveland continues to be used unofficially in subsequent boundary reviews as presented by the Boundary Commission for England to describe the area covered by the former county for the purpose of the rules which strongly deter cross-council constituencies (spanning more than one local authority within its area). The area covers the unitary authorities of Hartlepool, Middlesbrough, Redcar and Cleveland, and Stockton-on-Tees. The constituency boundaries used up to the 2005 United Kingdom general election were drawn up when it was a county. The area is divided into 6 parliamentary constituencies – 3 borough constituencies and 3 county constituencies.

2010 boundary changes
Under the Fifth Periodic Review of Westminster constituencies, the Boundary Commission for England decided to retain Cleveland's constituencies for the 2010 election, making minor changes to realign constituency boundaries with the boundaries of current local government wards and to reduce the electoral disparity between Stockton North and Stockton South.

Proposed boundary changes
See 2023 Periodic Review of Westminster constituencies for further details.

Following the abandonment of the Sixth Periodic Review (the 2018 review), the Boundary Commission for England formally launched the 2023 Review on 5 January 2021. Initial proposals were published on 8 June 2021 and, following two periods of public consultation, revised proposals were published on 8 November 2022. The final proposals were published on 28 June 2023.

The commission has proposed that the four unitary authorities which make up the former county of Cleveland be combined with the Borough of Darlington (previously considered with County Durham) to form a Tees Valley sub-division of the North East region. The proposals would involve Middlesbrough being renamed Middlesbrough and Thornaby East, and Stockton South renamed Stockton West.
