The league mainly focused on teams from the Baltic states, but teams from Sweden, Russia, Kazakhstan, Finland, and Belarus have participated in the Baltic League.

[1] For the 2015–16 season, the format of the BBL included a regular season composed by two groups of seven teams that competed in a round-robin competition system, with each team facing their opponent twice.

The teams qualified for the eight-finals based on their ranking after the regular season.

Out of the five teams who participated in FIBA Europe Cup competition – Ventspils, Juventus, Šiauliai, Tartu Ülikool/Rock and Pieno žvaigždės – the latter three did not qualify for the FIBA Europe Cup playoffs and thus started playing at the start of the BBL playoffs, seeded respectively first, second and third based on last season's results.

Baltic Basketball League also featured a Baltic Basketball League Cup competition before the beginning of the regular season since 2008.
