A corner kick, commonly known as a corner, is the method of returning the ball in a game of association football when the ball goes out of play over the goal line, without a goal being scored and having last been touched by a member of the defending team. The kick is taken from the corner of the field of play nearer to the place where the ball crossed the goal line.

Corners are considered to be a reasonable goal-scoring opportunity for the attacking side, though not as much as a penalty kick or a direct free kick near the edge of the penalty area.

A corner kick that scores without being touched by another player is called an Olimpico goal, or less commonly, Olympic goal.
