The 2021 Campeonato Tocantinense de Futebol was the 29rd edition of the Tocantins's top professional football league. The competition began on 20 February and was suspended in April due to the COVID-19 pandemic.[1] [2] [3] In October, the Federação Tocantinense de Futebol (FTF) confirmed the return of the tournament on 12 December.[4] The tournament ended on 30 December. Palmas were the defending champions but were eliminated in the semi-finals.
