Gaelic football, commonly referred to as "football" or "Gaelic", is a form of football played in Ireland. It is, together with hurling, one of the two most popular spectator sports in Ireland.

Gaelic football is played by teams of 15 on a rectangular grass pitch with H-shaped goals at each end. The primary object is to score by kicking or striking the ball with the hand and getting it through the goals. The team with the highest score at the end of the match wins. Players advance the ball up the field with a combination of carrying, soloing (dropping and then toe-kicking the ball upward into the hands), kicking, and hand-passing to their team-mates.

Gaelic football is also played in countries outside Ireland, often although not solely played by members of the Irish diaspora. It is increasing in popularity internationally. Teams from both London and New York compete in the annual All-Ireland Senior Football Championship, the highest level of the game.

International rules football, a hybrid of Gaelic football and Australian rules football, facilitates matches between Gaelic footballers and Australian-rules footballers. International rules is most prominently used for international representative matches between Ireland and Australia.
