List of European Parliament by-elections in the United Kingdom

By-elections to the European Parliament in the United Kingdom were held during the period when the United Kingdom used single-member, first-past-the-post constituencies to elect Members of the European Parliament from 1979 to 1999: they were required when a member resigned, died or was disqualified. Six by-elections were held in this period, all retained by the holding party.
