The International Tennis Federation (ITF)is the governing body of world tennis, wheelchair tennis, and beach tennis. It was founded in 1913 as the International Lawn Tennis Federation by twelve national tennis associations. As of 2016, there are 211 national and six regional associations that make up the ITF's membership.
The ITF's governance responsibilities include maintaining and enforcing the rules of tennis, regulating international team competitions, promoting the game, and preserving the sport's integrity via anti-doping and anti-corruption programs. The ITF partners with the Women's Tennis Association (WTA) and the Association of Tennis Professionals (ATP) to govern professional tennis.
The ITF organizes annual team competitions for men (Davis Cup), women (Billie Jean King Cup), and mixed teams (Hopman Cup), as well as tennis and wheelchair tennis events at the Summer Olympic and Paralympic Games on behalf of the International Olympic Committee. The ITF sanctions circuits that span age ranges (junior, professional men and women, and seniors) as well as disciplines (wheelchair tennis; beach tennis). In addition to these circuits, the ITF also maintains rankings for juniors, seniors, wheelchair and beach tennis.
