The first official regional club basketball tournament in Greece, took place in the year 1924.

The league was originally organized by the Hellenic Amateur Athletic Association (SEGAS).

The 1988–89 season, marked the first time that Greek Basket League teams were allowed to have foreign players on their rosters.

Also, Aris, led by Nikos Galis, Panagiotis Giannakis, and Slobodan "Lefteris" Subotić, was the dominant Greek club, and one of the most powerful European teams in the 1980s.

The first five aforementioned clubs (Panathinaikos, Olympiacos, AEK, Aris and PAOK), are also the most widely supported by fans in Greece.

However, it was ultimately decided that starting with the 2023–24 season, the aforementioned rotation of 6 out of the 7 foreign players on each team's roster, is also allowed in the league's playoffs.
