由歐洲多國共同建立的政治和經濟聯盟，主張歐洲多元一體，確保歐洲基本價值觀。加入的成員國會將部分國家主權交給歐盟決策，大多為經濟相關，例如貨幣、金融，內部市場等，有時候也包含外交政策。
27個成員國當中，有19國採用歐元為流通貨幣。另外還有取消邊境管制的《申根條約》，方便成員國公民享有在各國的工作權，持台灣護照亦可免簽證進出申根成員國。有些國家雖不是歐盟成員，但同樣可使用歐元及加入申根條約。
歐盟也面臨許多困境。最大問題是歐洲各地疑歐派興起，英國脫歐便是最明顯例子。另外像歐債危機、歐洲移民危機等，皆挑戰以德法為首的歐盟向心力。

Year of Establishment: 1993

The European Union is a political and economic multinational union founded on the philosophy of pluralistic unity to ensure the fundamental European values. The member states relinquish partial state sovereignty to the institution’s decision-making process, mostly regarding economic affairs, such as currency, finance, and internal markets. Sometimes the process also extends to foreign policies. 19 out of 27 member states have adopted the euro currency. The Schengen Agreement also lifted border control, allowing citizens of member states to seek employment freely across EU states. Taiwanese passport holders can also enter and exit the Schengen countries without a visa. Some of the other European countries also use the Euro and have signed the Schengen Agreement despite not being members of the EU. 

The union also has a lot of challenges on its plate. The biggest challenge of them all is the rise of Eurosceptics across the continent. Brexit is one of the most notable examples. Other challenges like the eurozone crisis and the European debt crises have both tested the solidarity of the Germany-and-France-led European Union.
