Pro-Europeanism in the context of the European Union and the process of European integration refers to a political orientation favourable of the EU policy and the integration process.
As such it would be the antonym of Euroscepticism, referring to political attitudes sceptical of or opposed to European integration (and not the more generic term "Anti-Europeanism" which may refer to attitudes to transatlantic relations within the US foreign policy).
