Croke Park is a Gaelic games stadium in Dublin, Ireland. Named after Archbishop Thomas Croke, it is referred to as Croker by GAA fans and locals. It serves as both the principal national stadium of Ireland and headquarters of the Gaelic Athletic Association (GAA). Since 1891 the site has been used by the GAA to host Gaelic sports, including the annual All-Ireland in Gaelic football and hurling.

Thomas William Croke D.D. was the second Catholic Bishop of Auckland, New Zealand (1870–74) and later Archbishop of Cashel and Emly in Ireland. He was important in the Irish nationalist movement especially as a Champion of the Irish National Land League in the 1880s. The main Gaelic Athletic Association stadium in Dublin is named Croke Park, in his honour.
