List of parliamentary constituencies in West Yorkshire

The English ceremonial county of West Yorkshire is divided into 22 parliamentary constituencies: 12 borough constituencies and 10 county constituencies.

Constituencies
Does not included Selby and Wetherby and Easingwold, which are predominantly in North Yorkshire.

2010 boundary changes
Under the Fifth Periodic Review of Westminster constituencies, the Boundary Commission for England decided to reduce the number of seats in West Yorkshire from 23 to 22, leading to significant changes in the Cities of Leeds and Wakefield, with the abolition of Elmet, Morley and Rothwell, Normanton, and Pontefract and Castleford and the creation of Elmet and Rothwell, Morley and Outwood, and Normanton, Pontefract and Castleford. Bradford North was renamed Bradford East.

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 West Yorkshire be combined with North Yorkshire as a sub-region of the Yorkshire and the Humber Region, resulting in the creation of two new cross-county boundary constituencies: Selby which comprises the majority of North Yorkshire district of Selby and includes the City of Leeds ward of Kippax and Methley; and a new constituency named Wetherby and Easingwold which includes the City of Leeds wards of Harewood and Wetherby. As a consequence, the following changes are proposed: Elmet and Rothwell is abolished; Wakefield is reconfigured to include the towns of Rothwell and Outwood and is renamed Wakefield and Rothwell; Morley and Outwood becomes Leeds South West and Morley; a new constituency named Ossett and Denby Dale is created; and the town of Normanton is transferred from Normanton, Pontefract and Castleford to Hemsworth, resulting in the two new constituencies of Pontefract, Castleford and Knottingley, and Normanton and Hemsworth. Elsewhere, Batley and Spen, and Dewsbury are realigned to form Dewsbury and Batley, and Spen Valley, and Leeds West and Pudsey are abolished, with parts of each forming Leeds West and Pudsey. Leeds Central effectively becomes Leeds South and a new constituency named Leeds Central and Headingley is created. Although its boundaries are unchanged, it is proposed that Keighley is renamed Keighley and Ilkley.
