All GAA club games have been suspended with immediate effect.
There is no timeframe for the suspension.
Clubs have been notified of the decision, which was by the GAA's Management Committee.
In the correspondence, the GAA said the decision has been taken "in the interest of public safety following a number of incidents that have been brought to our attention in recent days."
It continued: "In particular, post-match celebrations and a lack of social distancing at certain events have proved disappointing and problematic. This directive applies to all ages and all grades across the island."
A video has surfaced online of celebrations after Blackrock won the Cork Senior Hurling Championship yesterday.
The GAA statement also said that the club social centres and bars are also to close.
The statement concluded: "Training will continue to be permitted as per the guidelines outlined for the relevant levels in the Government's National Framework for Living with Covid 19 and relevant guidelines in the Six Counties. The GAA will continue to monitor the situation in the coming days and weeks, regarding changes in government guidelines, before liaising with our units accordingly."
The statement follows a statement this morning from Cork County GAA Board, appealing to clubs and supporters not to engage in celebrations which breach current public health guidelines.
