LNB Pro B is the second-tier professional basketball league in France, operating under the umbrella of the Ligue Nationale de Basket. It serves as a platform for teams to compete for promotion to the top league, LNB Pro A, and features a mix of established clubs and emerging talent. The league typically consists of around 14 teams that play a regular season followed by playoffs. The top teams at the end of the season have the opportunity to move up to LNB Pro A, while the lower-ranked teams may face relegation to the lower divisions.
