Preseli Pembrokeshire was a seat and constituency of the House of Commons of the Parliament of the United Kingdom. The Preseli Pembrokeshire Senedd constituency was created with the same boundaries in 1999. Its last MP, who held the seat since 2005, was the Conservative Stephen Crabb, who was Secretary of State for Work and Pensions (Work and Pensions Secretary) from March to July 2016. The seat was held by Labour's candidate from its creation in 1997 until 2005. The Labour and Conservative parties have won at least 27.7% of the vote apiece since its 1997 creation, with the next-placed parties having reached a maximum of 14.5% of the vote to date in a generally broad field. The seat attracted five candidates in 2010, eight in 2015 (an election in which five of the deposits were refunded and three lost) and seven in 2017. At the 2017 election, Crabb's majority was the 27th closest out of the 650 Commons seats, 0.8% or 314 votes. In 2019, there were four candidates; Crabb retained the seat with an increased majority. 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 Ceredigion Preseli and Mid and South Pembrokeshire.

Constituency profile

The seat was predominantly rural with both Welsh and English speaking areas. Milford Haven has a significant port and oil industry, and tourism is also a key sector due to the Pembrokeshire Coast National Park. The seat was less affluent than the UK average.

Boundaries

The constituency was created in 1997 from parts of the seats of Ceredigion and Pembroke North and Pembroke.
