Upper Bann is a parliamentary constituency in Northern Ireland, which is represented in the United Kingdom House of Commons. The current MP is Carla Lockhart of the DUP. Constituency profile Upper Bann includes the post-industrial towns of Portadown, Craigavon, and Lurgan. Boundaries 1983–1997: The District of Craigavon, and the District of Banbridge wards of Ballydown, Central, Edenderry, Gilford, Laurencetown, Loughbrickland, and Seapatrick. 1997–present: The District of Craigavon, and the District of Banbridge wards of Ballydown, Banbridge West, Edenderry, Fort, Gilford, Lawrencetown, Loughbrickland, Seapatrick, and The Cut. The seat was created in 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 Armagh and South Down. It was barely changed in further revisions in 1995 and covers the entirety of the district of Craigavon as well as part of Banbridge. In 2005, the Boundary Commission published provisional recommendations for modifying the boundaries of constituencies in Northern Ireland. It proposed transferring two small parts of Upper Bann to South Down and Lagan Valley. Following public consultation, the Commission revised its proposals which were finally passed through Parliament by means of the Northern Ireland Parliamentary Constituencies Order.

The constituency has a unionist majority, though the combined votes for nationalist parties have reached around 35% in elections. The Ulster Unionist Party has traditionally been dominant though it has been supplanted by the Democratic Unionist Party in recent years. The constituency contains Portadown and Drumcree, key locations for the Orange Order and elections to both local councils and the Northern Ireland Assembly have seen independent candidates standing on issues related to Orange Order parades performing well. In 1990 the sitting MP, Harold McCusker, died and the subsequent by-election was noticeable as for the first time since the early 1970s two major UK political parties stood in a Northern Ireland parliamentary election, the Conservatives and the rump of the Social Democratic Party. However the result was disappointing for the Conservatives, whilst the SDP polled a mere 154 votes. In that by-election David Trimble was elected and five years later he became leader of the Ulster Unionist Party. Trimble's leadership came in for much criticism from the rival Democratic Unionist
