:Cardiff West (UK Parliament constituency)

Until 2024 Cardiff West was entirely within the boundaries of the City of Cardiff, though in 2024 (as a result of the 2023 Review of UK constituences) it gained the Rhondda Cynon Taf ward of Pontyclun.{{cite news |date=22 May 2024 |title=MP seat changes in Wales: New boundaries and constituency names to be used for first time |url=https://www.itv.com/news/wales/2024-05-22/mp-seat-changes-in-wales-new-boundaries-and-constituency-names-to-be-used |access-date=2024-05-31 |work=ITV News}}

1950–1974: The County Borough of Cardiff wards of Canton, Ely, Grangetown, Llandaff, and Riverside.

1974–1983: The County Borough of Cardiff wards of Canton, Ely, Llandaff, Grangetown, Plasmawr, and Riverside.

1983–2010: The City of Cardiff wards of Caerau, Canton, Ely, Fairwater, Llandaff, Radyr and St Fagans, and Riverside.

2010–2024: The City of Cardiff wards of Caerau, Canton, Creigiau and St Fagans, Ely, Fairwater, Llandaff, Pentyrch, Radyr, and Riverside.

2024–present: As above with the addition of the Rhondda Cynon Taf ward of Pontyclun (as it existed on 1 December 2020), transferred primarily from Pontypridd.{{Cite web |title=The Parliamentary Constituencies Order 2023 |url=https://www.legislation.gov.uk/uksi/2023/1230/made |at=Schedule 4 (Wales)}}

Following local government boundary reviews which came into effect in May 2022,{{Cite web |title=The City and County of Cardiff (Electoral Arrangements) Order 2021 |url=https://www.legislation.gov.uk/wsi/2021/1160/schedule}}{{Cite web |title=The County Borough of Rhondda Cynon Taf (Electoral Arrangements) Order 2021 |url=https://www.legislation.gov.uk/wsi/2021/1080/schedule}} the constituency now comprises the following from the 2024 general election:{{Cite web |title=Election Maps |url=https://www.ordnancesurvey.co.uk/election-maps/gb/ |access-date=2025-03-09 |website=www.ordnancesurvey.co.uk}}

• The City and County of Cardiff wards of Caerau, Canton, Ely, Fairwater, Llandaff, Pentyrch and St Fagans, Radyr, and Riverside.
• The County Borough of Rhondda Cynon Taf wards of Pontyclun Central, Pontyclun East, and Pontyclun West (part).

Until 2024 Cardiff West was entirely within the boundaries of the City of Cardiff.

Population areas within the constituency include Riverside, Pontcanna, St Fagans and Ely. There are some Conservative and Plaid Cymru-leaning areas in the north of the seat such as Creigiau and St Fagans, Pentyrch and Radyr, but the bulk of the seat comprises districts towards the centre of Cardiff such as Caerau, Canton, Ely and Riverside which are very strongly Labour.

A traditionally safe Labour seat, represented for 33 years by George Thomas (who became Speaker in 1976 and was re-elected without party affiliation in 1979). It has returned a Conservative only once, in the Tories' landslide year of 1983, when Stefan Terlezki became the MP.

Labour regained the seat at the next general election in 1987, when Rhodri Morgan was elected. After the creation of the Welsh Assembly Government, Morgan stepped down from his Westminster seat in 2001 to serve as leader of Welsh Labour and First Minister for Wales. Kevin Brennan retained the seat for Labour on Morgan's retirement from Westminster politics. Following the announcement of the date of the 2024 general election Brennan announced his retirement from politics.{{cite news |title=Labour MP Kevin Brennan says he is standing down |url=https://www.bbc.co.uk/news/articles/cl77djl4vqzo |work=BBC News |date=27 May 2024 |access-date=2 July 2024 }}
