The 1945–46 Panhellenic Championship was the 12th season of the highest football league of Greece and the first after the WW2.
The clubs that participated were the champions from the three founding football associations of the HFF: Athens, Piraeus and Macedonia.
Initially, with the completion of all 6 matches, Aris held the first place in the standings.
But then the HFF accepted the objections of his opponents for illegal use of the player Siotis (which he played in two clubs at the same season), awarding 2–0 in their favor, the last 3 of his 4 games (an away draw against AEK Athens and home wins against Olympiacos and AEK), while at the same time zeroed the club of Thessaloniki for those games.
For a few days, the ranking was formed with the declaration of the AEK as champion by the HFF and Aris bringing the issue to its general assembly.
