List of Gaelic Athletic Association stadiums
The following is a list of stadiums used by the Gaelic Athletic Association . The stadiums are ordered by capacity; that is, the maximum number of spectators each stadium is authorised by the GAA to accommodate.
Three of the stadiums above 35,000 capacity are used for Gaelic football and hurling provincial finals, while the largest stadium, Croke Park, is used for the All-Ireland Senior Championship Finals each year, and the semi- and quarter-finals of each sport. It is also used on occasion for the Leinster provincial finals and Ulster provincial finals in Gaelic football, and has been leased for non-GAA events.
Croke Park has hosted 124 of the 138 finals of the All-Ireland Senior Football Championship, and all finals since 1908, except for the 1947 All-Ireland Senior Football Championship Final, which was played at the Polo Grounds in New York City.
Similarly, Croke Park has hosted 120 of the 138 finals of the All-Ireland Senior Hurling Championship, and all finals since 1912, except in 1937, when it was held at FitzGerald Stadium in Killarney due to construction work at Croke Park, and in 1984, when it was held at Semple Stadium in Thurles, County Tipperary, to mark the centenary of the founding of the GAA in the town.
Fans are not usually segregated at GAA venues.
Below are the locations of the county stadiums for county teams that participate in either the All-Ireland Senior Hurling Championship or the All-Ireland Senior Football Championship.
