Somerton and Frome was a constituency^{[n 1]} in Somerset represented in the House of Commons of the UK Parliament.^{[n 2]}

It was formerly represented by David Warburton, who was elected as a Conservative, but latterly sat as an Independent after losing the Conservative whip in April 2022 following allegations of misconduct. Warburton resigned as an MP on 17 June 2023, thus triggering the first by-election in this constituency since its creation at the 1983 general election, which was won by Sarah Dyke of the Liberal Democrats.

Further to the completion of the 2023 Periodic Review of Westminster constituencies, the seat was abolished. Subject to major boundary changes - including incorporation of the town of Frome and surrounding rural areas in the former Mendip District into the newly created constituency of Frome and East Somerset, and the transferring in of the towns of Glastonbury and Street from the constituency of Wells (to be renamed Wells and Mendip Hills) to partly compensate - the constituency will be reformed as Glastonbury and Somerton, to be first contested at the 2024 general election.^[3]

This area has a mixed economy, including agriculture and high-tech defence related industries.^[4] In November 2012, it had below the national average proportion of jobseekers (3.8%) at 1.6% of the population.^[5]
