Table of political parties in Europe by pancontinental organisation

The majority of major political parties in Europe have aligned themselves into the pan-European political organisations listed below.

• Nine of these organisations have been legally recognized by the European Union as political parties at the European level:
  • European People's Party
  • Party of European Socialists
  • European Liberal Democrat and Reform Party
  • European Green Party
  • Party of the European Left
  • Alliance for Europe of the Nations
  • European Free Alliance
  • European Democratic Party
  • EUDemocrats
• The Nordic Green Left Alliance is a transnational federation of parties, not a pan-European political party per se, but it articulates a broadly uniform ideology and its membership is exclusive to it. As such, it is treated akin to one here.
• The European Democrats are an informal body who only express themselves as a subgroup in the European Parliament. They likewise enjoy a relative ideological uniformity and membership exclusive from the other organizations. They are also treated like the other pan-European political organizations in the below chart.

Only parties represented in national parliaments or the European Parliament are included in the below chart, while independents have been omitted. Please note that great ideological diversity can be found in most pan-European organizations, and individual country rows may not correspond with the heuristic left-right spectrum commonly used within its own political discourse.
