1990 Campeonato Brasileiro Série B

The 1990 Campeonato Brasileiro Série B was the second division of Brazilian football, played by 24 teams. It began in August 1990 and ended on December 6, 1990. Sport Recife won the tournament title, beating Athletico Paranaense in the finals.

Format
The 24 participants were divided into four groups of six teams each. The teams competed in round within groups and robin, qualifying to the next stage the top four of each shift. The four teams with the worst campaigns would be relegated to 1991 Série C, but no such tournament happened, as CBF decided to include 64 clubs in the 1991 Série B, and cancel the Série C of that year. The 16 qualified teams were divided into four groups with four teams each, playing in the group in turn and robin, qualifying the top two from each group to the next stage. The 8 qualified teams were divided into two groups of four teams each, playing in the group in turn and robin, qualifying the best of each group for the final. The top placed teams of their respective groups in the third stage played the finals. Both gained access to the 1991 Campeonato Brasileiro Série A.
