The 2020–21 UEFA Nations League A is the top division of the 2020–21 edition of the UEFA Nations League, the second season of the international football competition involving the men's national teams of the 55 member associations of UEFA. League A will culminate with the Nations League Finals in June 2021 to determine the champions of the competition.
2020–21 UEFA Nations League A
League phase: 3 September – 17 November 2020 Nations League Finals: 2–6 June 2021
The Nations League Finals will take place in June 2021 and be played in a knockout format, consisting of the semi-finals, third place play-off, and final. The semi-final pairings, along with the administrative home teams for the third place play-off and final, are determined by means of a draw. The host country will be selected among the four qualified teams by the UEFA Executive Committee, with the winners of the final crowned as the champions of the UEFA Nations League.
In the 2020–21 access list, UEFA ranked teams based on the 2018–19 Nations League overall ranking, with a slight modification: teams which were originally relegated in the previous season were ranked immediately below teams promoted prior to the format change. The seeding pots for the league phase will be based on the access list ranking.
