Some people may think it is a region because it has countries in it and all those countries are in the same part of the world, and some people think the European Union is the same thing as Europe. The European Union is not a region though. It is an organisation that has countries as members. There are many such organisations around the world. The UN is not a region, NATO is not a region, the Commonwealth is not a region, and neither is the European Union. Europe is a continent and you could say it is a region. A large amount of the countries in Europe are not in the European Union.
