The European Parliament Election, 1999 was the United Kingdom's part of the European Parliament election 1999. It was held on 10 June 1999. Following the European Parliamentary Elections Act 1999, it was the first European election to be held in the United Kingdom where the whole country used a system of proportional representation. In total, 87 Members of the European Parliament were elected from the United Kingdom.

The Conservatives won double the number of seats they had won in the previous European election, in 1994, while the Labour Party saw its seats reduced from 62 to 29. It was the first European Parliament election to be held since the 1997 general election which resulted in a change of government from Conservative to Labour. The Liberal Democrats saw their number of seats increase to 10 from just 2 in the previous election. The UK Independence Party (UKIP), Green Party and Plaid Cymru gained their first ever seats in the European Parliament.

Turnout was 24%, the lowest of any member state in the 1999 election where the EU average was 49.51%. It was also the lowest of any European election in the United Kingdom, and the lowest of any member state until the 2009 election.
