Liga de Desenvolvimento de Basquete (LDB) (English: Developmental Basketball League) is an Under-20 age version of the top-tier level Brazilian men's professional basketball league, the Novo Basquete Brasil (NBB). The players need to be 20 years old and under to play in this tournament. It is a way to discover new players for future Brazilian national team generations, and for new young talents to be developed for the main teams of the Novo Basquete Brasil (NBB).

However, not all the teams that make up the NBB also compete in the LDB, due to not having competitive teams in the lower Brazilian basketball league categories. So some teams focus instead on the training of their young athletes, or participate as guests, and can still help to produce good future players for Brazilian basketball. LDB receives support from the Brazilian Federal Government to be organized.
