The Greek Basketball League (abbreviated as GBL), and also known as the Stoiximan Greek Basketball League (GBL) for sponsorship reasons, is the first tier level professional basketball league in Greece. It is run by the Hellenic Basketball Association (abbreviated as HEBA; Greek: ΕΣΑΚΕ), under the legal authority of the Hellenic Basketball Federation (abbreviated as HBF; Greek: Ε.Ο.Κ.). Over the years, the league has previously been known by several different names, which have included: the Panhellenic Basketball Championship or Greek Basketball Championship, the Panhellenic Basketball First Category Championship (1st) (A) or Greek Basketball First Category Championship (1st) (A), the Greek Alpha National Basketball Category Championship (A), the Greek Alpha1 National Basketball Category Championship (A1), the HEBA Alpha1 (A1), and most recently, the Greek Basket League. The league's current official main sponsor is Stoiximan.
The GBL is the highest-tier level of the Greek league system. The GBL plays under FIBA rules and currently consists of 12 teams, with each season's lowest-placed team being relegated to the A2 Basketball League, and then being replaced by the winner of the playoffs of that tier. The league runs from October to June, with teams playing 22 games each during the regular season, and the top 8 placed teams in the regular season standings then competing in the league's playoffs.[1] The first official Greek Basketball Championship was held in the 1927–28 season. The league held a competition in which the teams of the league played under a format with a nationwide schedule, for the first time, in the 1963–64 season. The league first held a playoff round in the 1986–87 season. The league first allowed foreign (non-Greek) players, in the 1988–89 season. The league first became a fully professional competition in the 1992–93 season, and that was also when its competition status was officially changed from the amateur category, to the professional category.
Historically, the GBL has been ranked as one of the top 3 level national domestic leagues in European basketball, since the league rankings began. For further information, see historical European national basketball league rankings, and European national basketball league rankings.
