The 1946–47 Greek Football Cup was the fifth edition of the Greek Football Cup. It was the first Greek Cup tournament to be held after the end of World War II. The competition culminated with the Greek Cup Final, held at Leoforos Alexandras Stadium, on 8 June 1947. The match was contested by Olympiacos and Iraklis, with Olympiacos winning by 5–0.^[1]

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.

The 5th Greek Cup Final was played at the Leoforos Alexandras Stadium.
