The Derry County Board of the Gaelic Athletic Association (GAA) (Cumann Lúthchleas Gael Coiste Chontae Dhoire) or Derry GAA is one of the 32 county boards of the GAA in Ireland. It is responsible for Gaelic games in County Londonderry in Northern Ireland (the GAA refers to the county as Derry). The county board is also responsible for the Derry county teams.

Football is the most popular of the county board's Gaelic games. The county football team won an All-Ireland Senior Football Championship (SFC) in 1993; it was the fourth from the province of Ulster to do so, following Cavan, Donegal and Down. The county team has also won seven National League titles and nine Ulster Championship titles.

However, Derry is also regarded as a small dual county.

According to a 2015 TUD study by Shane Mangan, Derry had slightly more than over 9,100 players.
