Format
The 2021 Campeonato Amazonense is divided into two stages:
First Stage
Standard round-robin, in which all teams play each other once. The worst two teams of the stage are relegated to the second division, while the other eight teams advance to the second stage.
Second Stage
The best teams play a two-legged knockout stage, with the best placed team of the match having the second leg at home. The winner of the Finals is declared the champion.
As in any other Brazilian soccer championship, the format can change every year.
