2017 Campeonato Carioca

The 2017 Campeonato Carioca was the 114th edition of the top tier of the Campeonato Carioca, organized by FFERJ (Federação de Futebol do Estado do Rio de Janeiro, or Rio de Janeiro State Football Federation). The top four teams not otherwise qualified through national and international tournaments qualified for the 2018 Copa do Brasil. The top two teams not already playing in the Campeonato Brasileiro Série A, Série B or Série C qualified for the 2018 Campeonato Brasileiro Série D.

Unlike previous editions of the Campeonato Carioca, there was a preliminary stage played by the bottom four teams from the previous edition and the top two teams from the 2016 Campeonato Carioca Série B. The top two teams from the preliminary stage qualified for the main competition, while the remaining four teams competed in a relegation playoff round. The bottom two teams in the relegation playoff round were relegated to the 2017 Campeonato Carioca Série B1. The main competition consisted of two phases, the Taça Guanabara and the Taça Rio. In the Taça Guanabara, the teams were divided into two groups of six, with each team playing against every other team in their own group once; the top two teams from each group qualified to a single-legged knockout round. In the Taça Rio, the same groups of six had each team play every team from the other group once; the top two teams from each group qualified to a single-legged knockout round. The top four teams in the overall standings, including both the Taça Guanabara and the Taça Rio, then qualified for a final stage to determine the champion of the Campeonato Carioca; this consisted of a single-legged semifinal and a two-legged final.
