The 1980 Greek Super Cup was the 1st edition of the Greek Super Cup, an association football match contested by the winners of the previous season's Alpha Ethniki and Greek Cup competitions. The match took place on 29 May 1980 at Karaiskakis Stadium. The contesting teams were the 1979–80 Alpha Ethniki champions, Olympiacos and the 1979–80 Greek Cup winners, Kastoria. The institution was organized by PSAT as an unofficial match, but it was later officially recognized. The match was held just four days after the cup final and five days after the championship play-off between Olympiacos and Aris.
