A team sport is a type of sport where the fundamental nature of the game or sport necessitates the participation of multiple individuals working together as a team, and it is inherently impossible or highly impractical to execute the sport as a single-player endeavour. In team sports, the cooperative effort of team members is essential for the sport to function and achieve its objectives. The objective often involves teammates facilitating the movement of a ball or similar object in accordance with a set of rules in order to score points. Examples are basketball, volleyball, rugby, water polo, handball, lacrosse, cricket, baseball, and the various forms of football and hockey. These sports emphasize teamwork, strategy, and coordination among team members while competing against opposing teams to achieve a common goal. Team sports do not include individual or individual-to-team events within a sport.

Sport is a form of physical activity or game. Often competitive and organized, sports use, maintain, or improve physical ability and skills. They also provide enjoyment to participants and, in some cases, entertainment to spectators. Many sports exist, with different participant numbers, some are done by a single person with others being done by hundreds. Most sports take place either in teams or competing as individuals. Some sports allow a "tie" or "draw", in which there is no single winner; others provide tie-breaking methods to ensure one winner. A number of contests may be arranged in a tournament format, producing a champion. Many sports leagues make an annual champion by arranging games in a regular sports season, followed in some cases by playoffs.
