欧洲议会议员（Member of the European Parliament）是指欧洲议会的代表。欧洲议会成立之初，会员国从自己的国民议会成员选出欧洲议会议员。然而自1979年以来，欧洲议会议员直接由普选选出。每个成员国都创建了自己选出欧洲议会议员的方式，但选举日期全欧盟统一，一些国家的选举制度随着时间的推移和发生变化。主要的选举方式包括地区和全国的政党比例代表制或单记让渡投票制。

A Member of the European Parliament (MEP) is a person who has been elected to serve as a popular representative in the European Parliament.

When the European Parliament was first established, MEPs were directly appointed by the governments of member states from among those already sitting in their own national parliaments. Since 1979, however, MEPs have been elected by direct universal suffrage. Each member state establishes its own method for electing MEPs – and in some states this has changed over time – but the system chosen must be a form of proportional representation. In some member states the MEPs are elected to represent a single national constituency; in others they are elected from sub-national regions.
