The 2021 Campeonato Carioca de Futebol was the 118th edition of the top division of football in the state of Rio de Janeiro. The competition is organized by FERJ. It began on 16 January 2021 and ended on 22 May 2021. The tournament was played behind closed doors due to the coronavirus pandemic in Brazil. In order to lower the number of matches to be played, this edition of the Campeonato Carioca faced another change in format and regulations.[1]
