Austral Basketball League

The Austral Basketball League (French: Ligue Austral de Basketball, Spanish: Liga Austral de Baloncesto) is the unified top professional basketball division of the Eusloidian and Jysanian basketball league system. It was founded as a replacement of both countries's top basketball leagues in 1972 and it is jointly administrated by the Eusloidian Basketball Federation and the Jysanian Basketball Federation.

The league is split into the Eusloidian Division (French: Division Eusloidiénne) and the Jysanian Division (Spanish: División Jisana) and it is played as a round-robin tournament, with the champion and runner-up of each division then playing the post-season Final Four to determine the season's champion and the last two teams of each division being relegated to their respective second division.
