All GAA club games at all levels have been suspended with immediate effect.
The GAA's Management Committee says the decision has been taken in the interest of public safety following a number of incidents that have been brought to its attention in recent days.
In a statement it says in particular, post-match celebrations and a lack of social distancing at certain events have proved disappointing and problematic.
The directive applies to all ages and all grades across the island.
Club social centres/bars are also to close.
The GAA will continue to monitor the situation in the coming days and weeks, regarding changes in government guidelines.
