The 2021 UEFA Nations League Finals was the final tournament 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. The tournament was held in Italy from 6 to 10 October 2021, and was contested by the four group winners of Nations League A. The tournament consisted of two semi-finals, a third place play-off and final to determine the champions of the UEFA Nations League. While originally scheduled for 2 to 6 June 2021, the tournament was pushed back due to the postponement of UEFA Euro 2020 to June and July 2021.
Portugal were the defending champions, having won the inaugural 2019 finals. However, they failed to qualify for the 2021 finals after finishing second in their group behind France.
