1983 Campeonato Gaúcho

The championship would have two stages.:^[2][1]

• First phase: The twelve clubs played each other in a double round-robin system. The eight best teams qualified to the Final phase, with the four best teams qualifying to a one-legged playoff to define the two teams that would receive one bonus point for the Final phase, and in addition to that, the two best teams from the hinterland earned one bonus point too.
• Final phase: The eight remaining teams played each other in a double round-robin system; the team with the most points won the title.

According to the regulations, the teams with the best performances would have the home advantage in the playoffs. However, since Grêmio and São Paulo had ended up tied in both points and goal difference, a playoff to define where the main playoff match would be played was held in neutral ground.^[1]
