The UK European Union Party (UKEU Party) was a minor pro-European political party in the United Kingdom, founded by lawyer Pierre Kirk in the prelude to the 2019 European Parliament election in the United Kingdom.

[1] The party stood candidates in three constituencies (London, North-West England, South East England)[3] many of whom were from other EU member states.

Kirk stood as a UKEUP candidate in the 2019 Peterborough by-election, coming 14th out of 15 candidates and winning just 25 votes.

[5] Aside from its strong pro-European stance, Kirk described the party as a socially liberal but fiscally conservative centrist group that endorsed policies such as improving healthcare, freedom of movement, a removal of tuition fees, and a boost to affordable housing.

[1] The party endorsed a unified EU defence force and the UK's adoption of the euro.
