The European Parliamentary Elections Act 1999 is an act of the Parliament of the United Kingdom. The Act amended the procedures on European elections in the United Kingdom. It received Royal Assent on 14 January 1999, after the Parliament Acts 1911 and 1949 had been invoked, as the House of Lords had rejected the bill six times, refusing to accept the change in the electoral system proposed. The Parliament Acts are rarely invoked; the European Parliamentary Elections Act was only the fifth statute since 1911 enacted under their provisions, and only the second since the Parliament Act 1949.
The 1999 European Parliament election was the United Kingdom's part of the European Parliament election 1999. It was held on 10 June 1999.

The apportionment of seats within the European Parliament to each member state of the European Union is set out by the EU treaties. According to European Union treaties, the distribution of seats is "degressively proportional" to the population of the member states, with negotiations and agreements between member states playing a role. Thus the allocation of seats is not strictly proportional to the size of a state's population, nor does it reflect any other automatically triggered or fixed mathematical formula. The process can be compared to the composition of the electoral college used to elect the President of the United States of America in that, pro rata, the smaller state received more places in the electoral college than the more populous states.
