Cork City will take on Scottish giants Celtic on 8 July in SuperValu Páirc Uí Chaoimh in an event led by Cork GAA as a fundraiser.
The Cork Super Cup is a joint initiative between the GAA outfit and sports marketing agency Druid Sport. City will also profit from the fixture.
The match will only be the third ever soccer match to be staged at the grounds.
The winners will lift a specially commissioned Cork Super Cup trophy, designed by Cork GAA legend Ger McCarthy.
The organisers estimate that the economic return from the fixture could be in the region of €6 million. The seated capacity of Páirc Uí Chaoimh is over 21,000 seated, with standing areas also available.
Kevin O’Donovan, CEO of Cork GAA, said "everyone wins" by coming together with City and Celtic: "We are fortunate that one of the world’s most successful soccer teams has agreed to return to Cork, and we have been engaging with Cork City FC to ensure that both sets of fans really enjoy the experience.
"Every event such as this generates funding streams that we can reinvest in the stadium, and in our own games, so everyone wins."
Celtic have played Cork City in friendlies on Leeside before, including a famous 2-0 victory for the home side during a visit in 1992.
A team of Celtic and Manchester United legends had taken on a team of Ireland legends at the stadium in 2018, in memory of the late Liam Miller.
Celtic were last in Ireland in October as they beat Sligo Rovers 3-2 with Luis Palma scoring a hat-trick in The Showgrounds.
