The United Kingdom's component of the 1999 European Parliament election was held on Thursday 10 June 1999. They were the first nationwide poll since the 1997 United Kingdom general election.

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

The results saw the Labour government lose over half their seats with the Conservatives becoming the largest party. These elections also saw the emergence of the UK Independence Party and the Green Party of England and Wales.

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