The 2017–18 NBB season was the 9th season of the Novo Basquete Brasil, the Brazilian basketball league.[2] Once again this tournament was organized entirely by the Liga Nacional de Basquete (LNB). The NBB also qualified teams for international tournaments such as Liga Sudamericana and FIBA Americas League.
This season fifteen teams played each other in the regular season. At the end of the home and away matches round the top four teams qualified for the quarterfinals of the playoffs automatically, while the teams finishing in the 5th and 12th place participated in the first round of the playoffs to determine the other four teams in the quarterfinals, in a five-match series. This season maintained 16/17's playoff method of best of 5 games, played on the 1-2-1-1 format.
For this season, the last regular season placed team is relegated to the 2019 Liga Ouro, the NBB's second tier division. Also, only the 2018 Liga Ouro winner receives the right to play in the NBB 2019–20 season.
