2020 Campeonato Brasileiro Série A

The 2020 Campeonato Brasileiro Série A (officially the Brasileirão Assaí 2020 for sponsorship reasons) was the 64th season of the Campeonato Brasileiro Série A, the top level of professional football in Brazil, and the 17th edition in a double round-robin since its establishment in 2003. The competition was originally scheduled to begin on 3 May and end on 6 December, however due to the COVID-19 pandemic the tournament was rescheduled, starting on 8 August 2020 and ending on 25 February 2021.

The top six teams as well as the 2020 Copa do Brasil champions qualified for the Copa Libertadores. The next six best-placed teams not qualified for Copa Libertadores qualified for the Copa Sudamericana and the last four were relegated to Série B for 2021. The match ball for the 2020 season was the Nike Merlin CBF 2020, which was presented by the Brazilian Football Confederation on 31 January 2020. Flamengo were the defending champions and successfully defended their title, winning their seventh championship on the last day of the season despite losing 2–1 to São Paulo, after Internacional drew with Corinthians at home by a 0–0 score.
