泛欧主义（英语：Pan-Europeanism）是指视欧洲为一个整体，主张统合欧洲或加强欧洲一体性的思想。在狭义上，泛欧主义由理察·尼古拉斯·冯·康登霍维-凯勒奇始自1920年代。这一思想在二战之后广为流行，是现在欧洲联盟等欧洲统合行为在思想上的基础。和泛欧主义相反的思想是欧洲怀疑主义。

Pan-European identity is the sense of personal identification with Europe. The most concrete example of pan-Europeanism is the European Union (EU). 'Europe' is widely used as a synonym for the EU, as 500 million Europeans (70%) are EU citizens; however, many nations that are not part of the EU may have large portions of their populations who identify themselves as European as well as their country nationality. Those countries are usually part of the older Council of Europe and have aspirations of EU membership. The prefix pan implies that the identity applies throughout Europe, and especially in an EU context, 'pan-European' is often contrasted with national.
