Bury St Edmunds was a constituency[n 1] in Suffolk from 1621 to 2024, most recently represented in the House of Commons of the UK Parliament from 2015 to 2024 by Jo Churchill, a Conservative.

Under the Representation of the People Act 1918, it was abolished as a borough and reconstituted as a division of the Parliamentary County of West Suffolk.

The closest contest since that year was in 1997 when the Labour Party candidate fell 368 votes, less than 1%, short of winning the seat in 1997 during Tony Blair's first landslide result.

Extended to the south-west, gaining western and northern parts of the abolished Sudbury Division of West Suffolk, including Haverhill.

Its boundaries did not match those of the former borough of St Edmundsbury, which included Haverhill (part of West Suffolk constituency), and excludes Stowmarket and Needham Market.
