The Acropolis International Basketball Tournament (also known as the Acropolis of Athens Tournament and the Acropolis Cup) (Greek: Τουρνουά Ακρόπολις) is an international basketball competition between national teams, which has been held annually since the year 1986 and takes place in Athens, Greece each summer. It takes place before the big official FIBA tournaments like the FIBA EuroBasket, the FIBA World Cup, and the Summer Olympic Games. The tournament is named after the world famous Acropolis of Athens. The competition is played under FIBA rules.
The tournament is organized by the Hellenic Basketball Federation, and it is sponsored by Eurobank. It is considered to be one of the most prestigious non-FIBA organized international basketball competitions that is competed between national teams.
To date, there have been 25 official Acropolis Tournaments that have been organized by the Hellenic Basketball Federation, plus the unofficial special edition 1991 FIBA Centennial Tournament. The Greek national team did not host the 2012 Acropolis Tournament, because it participated in the 2012 FIBA World Olympic Qualifying Tournament, and failed to qualify for the Olympics that year.
The 1991 Centennial Tournament was the special edition tournament that was organized jointly by FIBA Europe and the Greek Basketball Federation to commemorate the 100 year anniversary of the sport of basketball. It is not counted officially with the other 23 Acropolis Tournaments because it was not solely organized by the Greek Basketball Federation.
