The 1977 Greek Cup final was the 33rd final of the Greek Cup. The match took place on 22 June 1977 at Karaiskakis Stadium. The contesting teams were Panathinaikos and PAOK. It was Panathinaikos' thirteenth Greek Cup final in their 69 years of existence and PAOK's ninth Greek Cup final in their 51-year history. In the final, the clubs faced each other at the same stadium as in 1972, where after a spectacular match Panathinaikos won by 2–1, achieved the domestic double and completed a very successful season in general since they won the Balkans Cup, as well. The footballers of PAOK, protesting the refereeing of the match, refused to receive their medals, as a result of which they received a suspension of one matchday in the following season and in fact two on each matchday so that there would be no problem with the selection of the starting line-up.
