The UEFA Nations League is a biennial international football competition played by the senior men's national teams of the member associations of UEFA, the sport's European governing body.

The Union of European Football Associations 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 and Kazakhstan, as well as the West Asian countries of Cyprus, Armenia and Israel. UEFA consists of 55 national association members. Since 2022, due to the Russian invasion of Ukraine, FIFA and UEFA suspended all Russian national teams and clubs from any FIFA and UEFA competitions.
