Greek Basketball League

The Greek Basketball League (GBL), also known as Stoiximan GBL for sponsorship reasons, is the top-tier 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: ΕΟΚ).

The GBL follows FIBA rules, runs from October to June, and currently consists of 13 teams, each playing 24 games during the regular season, with the top 8 teams then competing in playoffs to determine the champion. The lowest-ranked team of the regular season is relegated to the Greek Elite League and replaced by the top team in that division, while a second team is promoted through playoffs.

The first official Greek basketball championship was held in the 1927–28 season, while its nationwide format was introduced in the 1963–64 season and the playoff round in the 1986–87 season. The league allowed foreign (non-Greek) players to participate for the first time in the 1988–89 season and became a fully professional competition in the 1992–93 season. Historically, the GBL has been ranked as one of the top 3 domestic leagues in European basketball.
