In sport, a goal may refer to either an instance of scoring, or to the physical structure or area where an attacking team must send the ball or puck in order to score points. The structure of a goal varies from sport to sport, and one is placed at or near each end of the playing field for each team to defend. For many sports, each goal structure usually consists of two vertical posts, called goal posts, supporting a horizontal crossbar. A goal line marked on the playing surface between the goal posts demarcates the goal area. Thus, the objective is to send the ball or puck between the goal posts, under or over the crossbar, and across the goal line. Other sports may have other types of structures or areas where the ball or puck must pass through, such as the basketball hoop. Sports which feature goal scoring are also commonly known as invasion games.

In sport, score is a quantitative measure of the relative performance of opponents in a sporting discipline. Score is usually measured in the abstract unit of points, and events in the competition can raise or lower the score of the involved parties. Most games with score use it as a quantitative indicator of success in the game, and in competition, a goal is often made of attaining a better score than one's opponents in order to win.
