Strangford is a parliamentary constituency in the House of Commons of the United Kingdom.
The constituency's current MP is Jim Shannon of the Democratic Unionist Party (DUP), who has served since the 2010 election.
Strangford covers the settlements either side of Strangford Lough.
The constituency has been represented by Unionist candidates since it was formed. There have not been significant votes for parties outside the traditional unionist block, although the Alliance has saved its deposit in every election.
The main interest in elections has been the contest between the Ulster Unionist Party (UUP) and the Democratic Unionist Party (DUP). Until the 2001 general election, the UUP were clearly ahead of the DUP in Westminster elections, but elections to regional assemblies and local government were much closer. In 2001 the sitting MP John Taylor retired and the contest to succeed him was fierce. The seat was won by Iris Robinson for the Democratic Unionist Party (DUP) and the subsequent 2003 assembly election saw the DUP increase their vote further.
The seat is strongly unionist, and one of 7 areas of Northern Ireland which voted to leave the European Union.
The seat was created after boundary changes in 1983, as part of an expansion of Northern Ireland's constituencies from 12 to 17, and was predominantly made up from parts of North Down.
In 1995, the Commission recommended abolishing the constituency and dividing it between North Down and new constituencies of Mid Down, and Castlereagh and Newtownards. This was successfully opposed in local enquiries.
From 2024, for the first time, the town of Strangford is included in the constituency having previously being in South Down.
Iris Robinson left the DUP shortly before taking the Chiltern Hundreds to leave the Commons. The seat was vacant from 13 January 2010 until the general election on 6 May 2010. Robinson resigned in January 2010 after a scandal involving financial dealings. However, no by-election was held, as the next general election was held in May 2010.
