Opinion polling on the United Kingdom's membership of the European Union (2016–2020)

Following the referendum in the United Kingdom on its membership of the European Union on 23 June 2016, polling companies continued to use standard questions in order to gauge public opinion on the country's relationship with the EU.

There have been opinion polls to gauge support for a second referendum, on whether to accept or reject the final Brexit deal.

Polling results vary depending on how the question is phrased: in general a "second referendum" is less popular than a "public vote" or similar descriptor.
