The Galway County Boards of the Gaelic Athletic Association (GAA) (Irish: Cumann Lúthchleas Gael Coiste Chontae na Gaillimhe) or Galway GAA are one of 32 county boards in Ireland; they are responsible for Gaelic games in County Galway, and for the Galway County teams.

Galway is one of the few dual counties in Ireland and competes at a similar level in both hurling and football codes. Prior to the amalgamation of the hurling and football district councils into one county council, both codes were previously administered by their separate boards in Galway, which was unusual for a dual county.

The county football team was the first from the province of Connacht to win an All-Ireland Senior Football Championship (SFC), but the second to appear in the final, after Mayo. It contests the All-Ireland Senior Football Championship through the Connacht Senior Football Championship. It is currently in Division 1 of the National Football League.

The county hurling team competes for the All-Ireland Senior Hurling Championship through the Leinster Senior Hurling Championship. It is currently in Division 1B of the National Hurling League.
