In June 2021, Donnarumma was included in Italy's squad for UEFA Euro 2020. In his first game at the competition, on 11 June against Turkey, he kept a clean sheet in a 3–0 win for Italy. In the semi-final against Spain on 6 July, following a 1–1 draw after extra-time, he saved Álvaro Morata's spot-kick to help Italy to a 4–2 penalty shoot-out victory, which allowed Italy to advance to the final of the tournament. On 11 July in the final against England at Wembley Stadium, following a 1–1 draw after extra-time, Donnarumma saved two spot kicks during the penalty shootout, including the decisive final kick, to win the tournament for Italy for the first time since 1968. For his performances throughout the competition, including keeping three clean sheets, making nine saves, and conceding only four goals in seven appearances, he was named "player of the tournament" by UEFA, the first time a goalkeeper had won the award.
