East Dunbartonshire (UK Parliament constituency)

East Dunbartonshire was a county constituency of the House of Commons of the Parliament of the United Kingdom (Westminster). It elected one Member of Parliament (MP) by the first past the post system of election. The seat is possibly best known for formerly being the constituency of Jo Swinson, the former Leader of the Liberal Democrats who was defeated at the 2019 general election.

This version of the constituency was first used at the 2005 general election. There was also an earlier East Dunbartonshire constituency, from 1950 to 1983.

Further to the completion of the 2023 review of Westminster constituencies, the seat was expanded and renamed Mid Dunbartonshire, and was first contested at the 2024 general election.
