There were no official nation-wide Greek Cup competitions prior to the 1975–76 season. However, there was a precursor tournament to the Greek Cup, called the
Attica State Cup, which was won by
AEK Athens, in the 1966–67 and 1970–71 seasons. The first official Greek Cup took place during the 1975–76 season. From the 1994–95 to 2003–04 seasons, the Greek Cup tournament used a
Final Four format. During that time, the Greek Cup competition format included a total of 62 teams; 14 from the
top-tier level
Greek Basketball League (GBL), 16 from the
2nd-tier level
Greek A2 Basketball League, and 32 teams from the third-tier level
Greek B Basketball League. Through the 2021–22 season, the top six placed teams from the previous season of the Greek Basketball League had an automatic
bye to the Greek Cup quarterfinals, while the other eight teams played in preliminary rounds for the other two quarterfinals places. The quarterfinals and onward rounds were played under a
single elimination format. Starting with the
2022–23 Greek Cup tournament, the top seven placed teams of the top-tier level Greek Basketball League's first half of the regular season, and the winners of the 2nd-tier level
Greek UNICEF Trophy, compete in a single elimination Final 8 format. == Cup winners ==
