Lagan Valley is a Northern Ireland parliamentary constituency in the House of Commons of the United Kingdom covering the area of the Lagan Valley including the south part of County Antrim and the north-west part of County Down.
Its MP since the 2024 general election is Sorcha Eastwood of the Alliance Party. [2] This was the first time since its creation it did not elect a unionist MP.
The seat was created in 1983, as part of an expansion of Northern Ireland's constituencies from 12 to 17, and was predominantly made up from parts of South Antrim and North Down in the area of the River Lagan. In their original proposals, in January 1980, the boundary commission proposed calling it "Lagan". In further revisions in 1995 it lost some areas to both Belfast West and Strangford.
