2020–21 AC Milan season

The 2020–21 AC Milan season was the 122nd season in the club's history and their 87th (109th overall) in the top-flight of Italian football. Milan competed in Serie A, the Coppa Italia, and the UEFA Europa League.

Season overview
On 22 July 2020, manager Stefano Pioli extended his expiring contract with Milan for two additional seasons. This came after multiple reports linked Ralf Rangnick to the club. The previous day, Milan had secured a play-off spot in the UEFA Europa League for the 2020–21 season thanks to an away win against Sassuolo.

On 1 October, Milan qualified for the group stage of the Europa League after defeating Primeira Liga side Rio Ave in a marathon 24-kick penalty shoot-out. The win also continued an unbeaten run for Milan in all competitions that stretched back to 8 March 2020.

On 5 November 2020, the club fell to its first defeat in 24 matches with a 0–3 loss at home to Lille in the Europa League. It was Milan's longest unbeaten streak in 24 years.

On 20 December 2020, Rafael Leao scored after 6.76 seconds in a championship match against Sassuolo. This was the fastest goal ever in Serie A and in the top 5 UEFA leagues.

On 23 December 2020, in a championship match against Lazio, Milan became the first team in over 70 years to score at least 2 goals in 15 consecutive league games, the record being 18 consecutive games.

After the winter transfers window, Milan remained without South American players active into main rosters, after the sales of Léo Duarte and Mateo Musacchio. It was the first time since 24 years (1997).

On the final day they secured qualification for the UEFA Champions League for the first time since the 2013-14 season
