Newport West (UK Parliament constituency)

Newport West (Welsh: Gorllewin Casnewydd) was one of two parliamentary constituencies for the city of Newport, South Wales, in the House of Commons of the Parliament of the United Kingdom. It elected one Member of Parliament (MP) using the first-past-the-post voting system. Paul Flynn, of the Labour Party, was the MP from the 1987 general election until his death on 17 February 2019. Consequently, a by-election was held in the constituency on Thursday 4 April 2019 and Ruth Jones of the Labour Party was elected.

The constituency was abolished as part of the 2023 Periodic Review of Westminster constituencies and under the June 2023 final recommendations of the Boundary Commission for Wales for the 2024 United Kingdom general election. Its wards were split between the existing Newport East constituency and a new constituency named Newport West and Islwyn.
