2018–19 Greek Basket League

The 2018–19 Greek betshop.gr Basket League was the 79th season of the Greek Basket League, the top-tier level professional club basketball league in Greece. The season started on 7 October 2018, and ended on 15 June 2019. Panathinaikos OPAP won the Greek Basket League championship for a record 37th time, after beating Promitheas Patras 3–0 in the Finals.

The season infamously featured a major feud between traditional rivals Panathinaikos and Olympiacos over refereeing decisions in the 2019 Greek Cup semifinals game between the two teams, which eventually culminated in Olympiacos also forfeiting their playoffs. Finally, Olympiacos withdrew from the championship.
