The Sligo County Board of the Gaelic Athletic Association (GAA) (Irish: Cumann Luthchleas Gael Coiste Chontae Shligigh) or Sligo GAA is one of the 32 county boards of the GAA in Ireland, and is responsible for Gaelic games in County Sligo. The county board is also responsible for the Sligo county teams.
The county football team plays in the Connacht Senior Football Championship but has only won three senior provincial titles, in 1928, 1975 and 2007. Sligo has never appeared in an All-Ireland final. The 1922 Championship is the closest it has come, defeating Roscommon, Mayo and Galway to win the Connacht title, and beating Tipperary in the subsequent All-Ireland semi-final that followed. However, "a flimsy technicality" led to a replay of the Connacht final against Galway, which Sligo lost.
As of 2009, there were 26 clubs affiliated to Sligo GAA — the second smallest, ahead of Longford, which had 24.
