The Gaelic Athletic Association is set up in Hayes's Hotel in Thurles, County Tipperary.

The Gaelic Athletic Association (GAA; Irish: Cumann Lúthchleas Gael [ˈkʊmˠən̪ˠ ˈl̪ˠuː(h)xlʲəsˠ ˈɡeːl̪ˠ]; CLG) is an Irish international amateur sporting and cultural organisation, focused primarily on promoting indigenous Gaelic games and pastimes, which include the traditional Irish sports of hurling, camogie, Gaelic football, Gaelic handball and rounders. The association also promotes Irish music and dance, as well as the Irish language.

As of 2014, the organisation had over 500,000 members worldwide, and declared total revenues of €65.6 million in 2017. The Games Administration Committee (GAC) of the Gaelic Athletic Association (GAA) governing bodies organise the fixture list of Gaelic games within a GAA county or provincial councils.

Gaelic football and hurling are the most popular activities promoted by the organisation, and the most popular sports in the Republic of Ireland in terms of attendances. Gaelic football is also the second most popular participation sport in Northern Ireland. The women's version of these games, ladies' Gaelic football and camogie, are organised by the independent but closely linked Ladies' Gaelic Football Association and the Camogie Association of Ireland respectively. GAA Handball is the governing body for the sport of handball, while the other Gaelic sport, rounders, is managed by the GAA Rounders National Council (Irish: Comhairle Cluiche Corr na hÉireann).

Since its foundation in 1884, the association has grown to become a major influence in Irish sporting and cultural life, with considerable reach into communities throughout Ireland and among the Irish diaspora.
