The United Kingdom's component of the 2004 European Parliament election was held on Thursday 10 June 2004. They were the first nationwide poll since the 2001 United Kingdom general election.

In England and Wales the votes were counted in each local authority, and the results were amalgamated for the regional lists. The votes in Scotland were counted in each Westminster constituency. These European elections were the second to be fought under proportional representation within Great Britain. The seats were allocated according to the d'Hondt system.

The election saw poor results for the Labour government and the opposition Conservative Party. These elections showed strength for the UK Independence Party who doubled their support. The Liberal Democrats fell to fourth place. The Green Party of England and Wales and the Scottish National Party stabilised winning two seats each and Plaid Cymru held its one seat. The British National Party and the Respect Party won a sizeable number of the votes but no seats.

The results in the Northern Ireland constituency were counted as one constituency using the single transferable vote.
