Leave.EU was a political campaign group that was first established to support the United Kingdom's withdrawal from the European Union in the June 2016 referendum. Founded in July 2015 as The Know, the campaign was relaunched in September of that year with its name changed to "Leave.eu" to reflect altered wording in the referendum question.

The campaign, along with rival organisation Vote Leave, aimed to be formally designated as the lead campaign for the "Leave" referendum vote by the Electoral Commission; however, on 13 April 2016, Vote Leave was designated as the official campaign.

The campaign was fined £70,000 in May 2018, after the Electoral Commission found that they failed to report at least £77,380 in spending. In February 2019, Leave.EU and Eldon Insurance owned by its founder Arron Banks were fined £120,000 over data law breaches.
