A Tennis Federation is an organization that governs and promotes the sport of tennis within a specific country or region. It is responsible for organizing tournaments, developing players, and ensuring that the rules of the game are followed. Federations also work to grow the sport at the grassroots level, encouraging participation among all age groups. One of the most prominent examples is the International Tennis Federation (ITF), which oversees international competitions like the Davis Cup and Fed Cup. National federations, such as the United States Tennis Association (USTA), play a crucial role in supporting local clubs and players, helping to nurture future tennis stars.
