Bridgwater and West Somerset is a constituency^{[n 1]} represented in the House of Commons of the UK Parliament since 2010 by Ian Liddell-Grainger, a Conservative.^{[n 2]}

Further to the completion of the 2023 Periodic Review of Westminster constituencies, the seat will be subject to boundary changes, with the loss of the area comprising the former District of West Somerset to the newly created constituency of Tiverton and Minehead. This will be partly offset by the addition of the communities of Burnham-on-Sea and Highbridge. As a consequence of these changes, the constituency will revert to its former name of Bridgwater, to be first contested at the next general election.

Bridgwater was one of the original parliamentary borough constituencies in England^{[n 3]} (with fifteen years of non-existence in the late 19th century after the seat was abolished for corruption in 1870 and being subsumed into a slightly larger seat on a review of Somerset's representation by the Boundary Commission^[3] in 1885).

In 2010 seven candidates stood. The second placed candidate was a Liberal Democrat, Theo Butt Philip, 11.2% ahead of the candidate from the Labour Party. The incumbent, Ian Liddell-Grainger, is a former Major in the Territorial Army, farmer and defence advisor.

In the snap election of 2017 Liddell-Grainger increased his majority to 15,000, the largest in the constituency's history, and Labour finished second in the seat for the first time.

The District of Sedgemoor wards of Bridgwater Bower, Bridgwater Eastover, Bridgwater Hamp, Bridgwater Quantock, Bridgwater Sydenham, Bridgwater Victoria, Cannington and Quantocks, East Poldens, Huntspill and Pawlett, King's Isle, North Petherton, Puriton, Sandford, West Poldens, and Woolavington, and the District of West Somerset.
