The 2020–21 season was Chelsea Women's 29th competitive season and 11th consecutive season in the FA Women's Super League, the top flight of English women's football. Chelsea competed in the domestic league as defending champions from the previous season. With a strong showing by the club, the title was successfully retained in addition to winning all domestic trophies offered – the FA Community Shield, the League Cup and the FA Cup. They also finished runners-up in the UEFA Champions League, which was their first appearance as finalists.

Community Shield.
In August 2020, the FA announced the return of the Women's FA Community Shield for the first time since 2008. The tie was contested between 2019–20 FA WSL champions Chelsea and Manchester City, who qualified as reigning 2019 FA Cup winners due to the unfinished nature of the 2019–20 Women's FA Cup. The match was part of a Wembley double-header on the same day as the men's equivalent.
