Union of European Football Associations (UEFA yoo-AY-fə; French: Union des associations européennes de football; German: Union der europäischen Fußballverbände) is one of six continental bodies of governance in association football. It governs football, futsal and beach football in Europe and the transcontinental countries of Turkey, Azerbaijan, Georgia, Russia and Kazakhstan, as well as some Asian countries such as Israel, Cyprus and Armenia. UEFA consists of 55 national association members. Because of the 2022 Russian invasion of Ukraine, FIFA and UEFA suspended all Russian national teams and clubs from any FIFA and UEFA competitions.

UEFA consists of the national football associations of Europe, and runs national and club competitions including the UEFA European Championship, UEFA Nations League, UEFA Champions League, UEFA Europa League, UEFA Europa Conference League, and UEFA Super Cup, and also controls the prize money, regulations, as well as media rights to those competitions.

Henri Delaunay acted as the first general secretary and Ebbe Schwartz as the first president. The current president is Aleksander Čeferin, a former Football Association of Slovenia president, who was elected as UEFA's seventh president at the 12th Extraordinary UEFA Congress in Athens in September 2016, and automatically became a vice-president of the world body FIFA.
