The Liga Sudamericana de Baloncesto (LSB), or FIBA Liga Sudamericana de Baloncesto (Portuguese: Liga Sul-Americana de Basquete, English: South American Basketball League), also commonly known as FIBA South American League, is the second-tier level South American professional basketball competition at the club level, with the first-tier level now considered the panamerican competition of the Champions League. The competition is organized by the South American Basketball Association (ABASU), which operates as a regional sub-zone of FIBA Americas. The winner of each year's competition gets a place at the upcoming edition of the Basketball Champions League Americas.
The league usually includes some national domestic champions, and some runners-up, from the best national leagues and basketball countries on the South American continent. Depending on the country, places may be awarded on the basis of performance in the previous season's national domestic league, or over the previous two or three national domestic seasons. The tournament has been played since 1996, aside from 2003, 2020 and 2021.
