The football (soccer) Campeonato Brasileiro Série B 1971, the second level of Brazilian National League, was played from September 12 to December 22, 1971.
The competition had 23 clubs.
The tournament consisted in a fusion of the already existing Torneio Centro-Sul and the Copa Norte-Nordeste, with the champions of each tournament facing off in the finals.
Villa Nova beat Remo on the finals, and was declared 1971 Brazilian Série B champions.
The relegation and promotion system hadn't been implemented yet, so no clubs were promoted.
