Cork GAA chairperson Tracey Kennedy has confirmed that stewards will confiscate any Confederate flags brought to its grounds.
Fans from the county commonly wave flags from other countries that include the colour red and Cork's nickname of 'The Rebels' may also have led to a sense of identification with the losing side in the American civil war.
While American defenders of the Confederate flag maintain it is merely a sign of pride in Southern heritage and a symbol of rebellion, critics argue that its presence represents support for the time and slavery, as well as the subsequent racist treatment of black people.
Stock-car racing NASCAR this week banned the flag from its racetracks and facilities, following the anti-racism protests that broke out across the US after the death in policy custody of black American man George Floyd.
Kennedy's predecessor Ger Lane urged fans not to fly the flag in 2017 and she told the Irish Times today that she regarded that as establishing a rule that would now be enforced.
"As far as I'm concerned, the Confederate flag is banned," she said.
"Ger’s statement in 2017 was very clear when he asked our supporters not to bring the flag to our grounds, not to use the flag, so as far as I’m concerned, it's banned.
"I’m happy to make that position explicit and say it’s banned from our grounds. It has no place in our grounds or in supporting Cork teams.
"We’re a community association and every part of the community is welcome in the GAA."
