South East Cambridgeshire (UK Parliament constituency)

South East Cambridgeshire was a constituency represented in the House of Commons of the UK Parliament from 2015 to 2024 by Lucy Frazer, a member of the Conservative Party who has served as Secretary of State for Culture, Media and Sport from 2023 to 2024. The constituency was established for the 1983 general election and was based on the cathedral city of Ely.

Under the 2023 periodic review of Westminster constituencies, the constituency was subject to major boundary changes. As a result, the seat was abolished for the 2024 general election, with the majority of the electorate being included in the new constituency of Ely and East Cambridgeshire.
