Most forms of football have a move known as a tackle. The primary and important purposes of tackling are to dispossess an opponent of the ball, to stop the player from gaining ground towards goal or to stop them from carrying out what they intend.

The word is used in some contact variations of football to describe the act of physically holding or wrestling a player to the ground. In others, it simply describes one or more methods of contesting for possession of the ball. It can therefore be used as both a defensive or attacking move.
