2025 Greek Basketball Super Cup
The 2025 Greek Basketball Super Cup is the 6th edition of the revived Greek professional domestic basketball super cup competition, under the auspices of the Hellenic Basketball Clubs Association (HEBA), and the 7th overall. The previous winner of the super cup was Olympiacos. The tournament was played from 26 to 27 September in Rhodes, Greece.
Olympiacos won the 2025 Greek Super Cup.
Panathinaikos B.C. who was meant to take place, could not compete in the tournament due to the scheduling conflict with the Pavlos Giannakopoulos Tournament in Australia. The Hellenic Basketball Federation refused to adjust the date despite being aware of the tournament for months, and the club was fined €20,000. ASK Karditsas B.C. was selected as a replacement.
