Open Europe

Open Europe was a British centre-right eurosceptic policy think tank with offices in London and Brussels, merging with the Policy Exchange think tank in 2020.

Its stated mission was to "conduct rigorous analysis and produce recommendations on which to base the UK's new relationship with the EU and its trading relationships with the rest of the world." It promoted democratically grounded economic, trade and investment policies which foster growth, employment and freedom under the rule of law. The think tank described itself as being "non-partisan and independent" but was also described as "eurosceptic".

The think-tank was set up in 2005 prior to the Lisbon Treaty by a group of British business to oppose further centralisation of power in the EU. It was a proponent of a flexible model for further European integration, allowing for EU member states to integrate with each other to different degrees and for powers to also be returned from the EU to member states. It adopted a neutral stance in the 2016 EU referendum in the UK.

In the wake of the UK's vote to leave the EU, Open Europe's research programme shifted to focus on three key aspects: the UK's new relationship with the EU, including trade, security and political cooperation; the most important opportunities for new trading relationships with nations outside the EU; productive international cooperation across areas such as immigration, research and development, cross-border investment and financial services.

Open Europe was described by The Economist in 2010 as "the Eurosceptic group that controls British coverage of the EU". It was ranked number 1. in the "International Affairs" Category in 2012 by Prospect magazine.
