The 1927–28 Panhellenic Championship was the first season of the highest football league of Greece. It was held with the participation of 3 teams, the champions of the founding Associations of the HFF, Athens, Piraeus and Macedonia, in which Atromitos, Ethnikos Piraeus and Aris finished first, respectively. Aris eventually won the championship.

At the beginning of the season, the HFF expelled Olympiacos from the championship of Piraeus and consequently the Panhellenic Championship. They also forbade the other clubs from playing against them even in friendly matches. However, Panathinaikos, AEK Athens and Apollon Athens expected financial income from the tournaments they organized with the participation of Olympiacos. Thus, on 31 October, the HFF expelled the other clubs, as well. As a result, Panathinaikos, Olympiacos and AEK Athens formed an alliance called POK, from the initials of the words Podosferikós Ómilos Kéntrou (Central Football Group) or from a paraphrase of the initials of their names; "Panathinaikos"-"Olympiacos"-"Konstantinoupόleos". In February 1928, Apollon Athens joined the alliance, with the press calling it "POKA". The non-participation of these clubs weakened the championship, as the fans preferred the international friendlies of the strong clubs and the tournaments that have been established during the holidays since then. The devaluation of their competitions forced the HFF to revoke their dismissals in July 1928 and from the next season the clubs returned to their championships. The point system was: Win: 2 points - Draw: 1 point - Loss: 0 points.

After the departure of Panathinaikos, AEK Athens and Apollon Athens, only 5 clubs participated. Atromitos, Goudi Athens, Athinaikos, Armeniki Enosis and Aias Athens. They played qualifying and final matches, without it being clear exactly what system was applied. The only thing that is certain is that after the qualifiers, Goudi and Atromitos qualified for the final.

The system of conduct was not clear, but it is known that a final match was held in May 1928, between the Ethnikos Piraeus and the Amyna Kokkinia, who seem to have been the only clubs in the league, after the punishment of Olympiacos. The final was held on 13 May 1928, at the Neo Phaliron Velodrome,^[1] where as the Ethnikos Piraeus led 4–1, the players of Amyna Kokkinia, not accepting their imminent defeat, caused incidents and the match was interrupted. The Piraeus Association stopped the final and declared Ethnikos Piraeus the champion.^[2]
