The Donegal County Board or Donegal GAA is one of 32 county boards of the Gaelic Athletic Association (GAA) in Ireland, and is responsible for the administration of Gaelic games in County Donegal.

The County Board is responsible for preparing the Donegal county teams in the various Gaelic sporting codes; football, hurling, camogie and handball.

The county football team was the third from the province of Ulster to win an All-Ireland Senior Football Championship (SFC), following Cavan and Down. It last won the All-Ireland SFC in 2012 and the Ulster Senior Football Championship in 2019. Donegal players comprised most of the 2012 All Stars Team of the Year, and the three nominations for the All Stars Footballer of the Year, ultimately won by Karl Lacey. In addition, having been invited to assist the Celtic soccer team in Scotland, Donegal manager Jim McGuinness became the first Gaelic football inter-county manager to have been offered a role at a professional sports team abroad. McGuinness's services have also been sought by Premier League soccer teams.

According to a 2015 TUD study by Shane Mangan, Donegal had the largest playing population in Ulster, with 14,000 players at that time.
