United States of Europe (, SUE) was a pro-European and liberal electoral list in Italy founded by Emma Bonino and Matteo Renzi to compete in the 2024 European parliament elections in Italy. The list, centred around More Europe and Italia Viva and including other centrist minor parties, was launched in March 2024 in Rome, with the aim of taking part in the 2024 European Parliament election. The list earned 3.77% of the vote but failed to break the 4% threshold of the vote, thus failing to gain any MEPs.
