The Big Three (Greek: Οι μεγάλοι τρεις, hoi megaloi treis) is the nickname of the three most successful sports clubs in Greece, all of whom are located within the so called Attica basin or Athens metropolitan area. The football teams of AEK, Olympiacos and Panathinaikos have a great rivalry, and are usually the main contenders for the title. Combined they share a total of 80 out of 88 Greek Football Championships ever played and generally they usually end up sharing the top three positions. A.E.K. has won 13 league titles (last won in 2023), Olympiacos has won a record 47 league titles (last won in 2022) and Panathinaikos has won 20 league titles (last won in 2010).
In recent years, due to PAOK’s success and their overall history and support, the term “Big Three”, has been largely replaced by the term “Big Four” by both the media and the public.
