The main bodies of the European Union and the Euratom are:

• the seven principal institutions of the European Union, including the one which is an international entity (the European Central Bank)
• other bodies of the EU established through primary (treaty) legislation, either as international law bodies (the European Investment Bank Group entities, the European University Institute, the European Stability Mechanism and the Unified Patent Court) or as bodies without juridical personality (the European Ombudsman, the advisory bodies to the European Union)
• the agencies, decentralised independent bodies and joint undertakings of the European Union and the Euratom, which are bodies of the EU established as juridical persons through secondary legislation,
• other bodies of the EU established through secondary legislation, which lack juridical personality (e.g. European Data Protection Supervisor)
• the inter-institutional services

Apart from them, some several other bodies exist.

The Treaty on European Union in Article 13 lists seven institutions of the European Union, including one which is an international entity (the European Central Bank).

A number of decentralised, executive and Eurarom agencies, decentralised independent bodies and joint undertakings exist, which are bodies of the EU or Euratom established as juridical persons through secondary EU legislation. These include the European Environment Agency and Europol.^[4]

There are also three inter-institutional bodies lacking juridical personality: the Publications Office, the oldest one, which publishes and distributes official publications from the European Union bodies;^[5] and the two relatively new: the European Personnel Selection Office (EPSO), a recruitment body which organises competitions for posts within Union institutions;^[6] and the European Administrative School, which provides specific training for the staff of Union institutions.^[7]

Another body is the anti-fraud office OLAF whose mission is to protect the financial interests of the European Union.^[8]

The European Data Protection Supervisor ensures the institutions respect citizens' privacy rights in relation to data processing.^[9]
