The 1930–31 Panhellenic Championship was the third season of the highest football league of Greece. Olympiacos emerged champion for the 1st time in its history. Apollon Athens, Ethnikos Piraeus and Iraklis qualified for the relegation play-offs for the Athenian, Piraeus' and Macedonian Association, respectively. All three prevailed over their opponents and remained in the national division.
The tournament was held as a national division, in which 8 teams from the 3 founding Associations of the HFF, participated and resulted as follows:
Athenian Championship: The 3 highest-ranked teams.
Piraeus' Championship: The 2 highest-ranked teams.
Macedonian Championship: The 3 highest-ranked teams.
These teams did not participate in the regional championships and their stay in the national division was judged by a play-off round. According to the regulations of the time, whoever finished in a lower position than the other teams of the same Association had to play a two-legged round against the winner of the corresponding regional championship to decide who will qualify for the next season's Panhellenic Championship.
The point system was: Win: 2 points - Draw: 1 point - Loss: 0 points.
