The2003–04 Greek Football Cup was the 62nd edition of theGreek Football Cup. That season's edition was entitled "Vodafone Greek Cup".^[1]

Each tie in theknockout phase, apart from the final, was played overtwo legs, with each team playing one leg at home. The team that scored more goals on aggregate over the two legs advanced to the next round. If the aggregate score was level, theaway goals rule was applied, i.e. the team that scored more goals away from home over the two legs advanced. If away goals were also equal, thenextra time was played. The away goals rule was again applied after extra time, i.e. if there were goals scored during extra time and the aggregate score was still level, the visiting team advanced by virtue of more away goals scored. If no goals were scored during extra time, the winners were decided by apenalty shoot-out. In the final, which were played as a single match, if the score was level at the end of normal time, extra time was played, followed by a penalty shoot-out if the score was still level.
The mechanism of the draws for each round is as follows:

• There are no seedings, and teams from the same group can be drawn against each other.
