1956–57 Panhellenic Championship
The 1956–57 Panhellenic Championship was the 21st season of the highest football league of Greece and one of the most interesting championships in the 50s and also one of the most discussed due to the punishment of Ethnikos Piraeus from the HFF. Olympiacos won their 13th championship after an interesting race with Panathinaikos which ended in a tie and therefore the title was decided by a play-off round in which Olympiacos won.
Compared to the previous season, the teams that participated in the final phase of the championship increased by 4 and resulted as follows:
- Athenian Championship: The first 3 teams of the ranking.
- Piraeus' Championship: The first 2 teams of the ranking.
- Macedonian Championship: The first 2 teams of the ranking.
- Regional Championship: The 2 winners.
- An additional position was secured after a play-off round between the third teams Piraeus' and Macedonian Championship.
