Handicapping, in sport and games, is the practice of assigning advantage through scoring compensation or other advantage given to different contestants to equalize the chances of winning. The word also applies to the various methods by which the advantage is calculated. In principle, a more experienced participant is disadvantaged, or a less experienced or capable participant is advantaged, in order to make it possible for the less experienced participant to win whilst maintaining fairness. Handicapping is used in scoring many games and competitive sports, including go, shogi, chess, croquet, golf, bowling, polo, basketball, and track and field events. Handicap races are common in clubs which encourage all levels of participants, such as swimming or in cycling clubs and sailing clubs, or which allow participants with a variety of standards of equipment. Often races, contests or tournaments where this practice is competitively employed are known as Handicaps.

Handicapping also refers to the various methods by which spectators can predict and quantify the results of a sporting match. The term is applied to the practice of predicting the result of a competition, such as for purposes of betting against the point spread. A favored team that wins by less than the point spread still wins the game, but bets on that team lose.

In either case the handicapper is the person who sets the handicaps for the activity.
