East Londonderry is a constituency in Northern Ireland represented in the House of Commons of the UK Parliament.

This is a mostly rural constituency stretching from the hill country of the Sperrin Mountains in the south to the Atlantic coast in the north; and from the suburbs of Derry city in the west to the River Bann in the east.

The inclusion of all of Coleraine Borough means that part of the East Londonderry constituency is actually in County Antrim.

The 2001 election was seen at a province-wide level as a battle over the Belfast Agreement, with the DUP opposed to it and most of the UUP in favour.

However, that situation was seemingly reversed in East Londonderry, in which the sitting Ulster Unionist MP, William Ross, was completely opposed to all involvement with the Agreement and its institutions, whilst the DUP candidate, Gregory Campbell, was a minister in the executive set up by the agreement.
