The 1938–39 Greek Football Cup was the third edition of the Greek Football Cup. The competition culminated with the Greek Cup Final, held at Leoforos Alexandras Stadium, on 28 May 1939. The match was contested by AEK Athens and PAOK, with AEK Athens winning by 2–1.^[1][2]

In the knockout phase, teams play against each other over a single match. If the match ends up as a draw, extra time will be played and if the match remains a draw a replay match is set at the home of the guest team which the extra time rule stands as well. That procedure will be repeated until a winner occurs.
The mechanism of the draws for each round is as follows:

• In the draw for the round of 16, the eight top teams of each association are seeded and the eight clubs that passed the qualification round are unseeded.
  The seeded teams are drawn against the unseeded teams.
• In the draws for the quarter-finals onwards, there are no seedings, and teams from the same group can be drawn against each other.
