The 2012 Campeonato Brasileiro Série A, officially referred to for sponsorship as the Brasileirão Petrobras 2012, was the 56th edition of Brazil's top professional football league. The competition followed the national double round‑robin format, bringing together twenty clubs that played home-and-away against each other. Corinthians entered the season as the defending champions from the 2011 season, while Fluminense secured the 2012 title, clinching the championship on 11 November 2012 for the club's fourth national crown.

Competition format and stakes

Teams were ranked primarily by points earned across 38 rounds. The league served as the main pathway for Brazilian clubs to qualify for continental tournaments the following year, including the Copa Libertadores and Copa Sudamericana. At the other end of the table, the four lowest-placed teams were relegated to the Campeonato Brasileiro Série B for the next season. The format emphasizes consistency over a full season rather than playoff-style finals.

Participants and organization

The 2012 field included traditional Brazilian powers alongside clubs promoted from Série B. Matches were staged in stadiums across Brazil, reflecting wide geographic representation and strong local followings. Fixture scheduling, television contracts, and sponsorship — notably the Petrobras naming rights that year — shaped the commercial and calendar context of the tournament.

Season narrative and highlights

Fluminense mounted a sustained campaign that delivered the championship with several crucial results late in the calendar, while other established clubs contested places for continental qualification. The title race and battle to avoid relegation produced memorable individual matches and shifting league positions throughout the season. Attention from fans and media concentrated on tactical battles, managerial changes at some clubs, and performances by national-team-level players who influenced outcomes.

Legacy and significance

The 2012 edition reinforced the Brasileirão's reputation as one of South America's most competitive national leagues, combining player development with high spectator interest. Winning the championship added to Fluminense's history and affected the composition of Brazil's representatives in regional competitions the next year.
