Provincial councils are organisational bodies within the Gaelic Athletic Association, each made up of several GAA counties. The provincial council is responsible for the organisation of club and inter-county competitions such as the provincial championships, and the promotion of Gaelic games within their region. There are five provincial councils in the GAA, four in Ireland (Connacht, Leinster, Munster, Ulster) and one in Britain.
The ultimate goal of the European county board is to become a provincial council.
