Gaelic football (Irish: Peil Ghaelach; short name Peil or Caid), commonly referred to as football or Gaelic, is a sport played between two teams of 15 players on a rectangular grass pitch.The objective of the sport is to score points by passing the ball through the other team's goals, a set of two upright posts separated by a crossbar 2.5 metres (8.2 ft) above the ground.

Players advance the football, a spherical leather ball, up the field with a combination of carrying, bouncing, kicking, hand-passing, and soloing (dropping the ball and then toe-kicking the ball upward into the hands). In the game, two types of scores are possible: points and goals. A point is awarded for kicking or hand-passing the ball over the crossbar, signalled by the umpire raising a white flag. A goal is awarded for kicking the ball under the crossbar into the net, signalled by the umpire raising a green flag. Positions in Gaelic football are similar to that in other football codes, and comprise one goalkeeper, six backs, two midfielders, and six forwards, with a variable number of substitutes.
