World Gymnastics, formerly the International Gymnastics Federation, is the body governing competition in all disciplines of gymnastics. Its headquarters is in Lausanne, Switzerland. It was founded on 23 July 1881 in Liège, Belgium, making it the world's oldest existing international sports organisation. Originally called the European Federation of Gymnastics, it had three member countries — Belgium, France and the Netherlands — until 1921, when non-European countries were admitted and the organization changed its name to the International Gymnastics Federation. Following other sport governing bodies, the organization took its current name in December 2025.
The federation sets the rules, known as the Code of Points, that regulate how gymnasts' performances are evaluated. Seven gymnastics disciplines are governed by the World Gymnastics: artistic gymnastics, further classified as men's artistic gymnastics and women's artistic gymnastics; rhythmic gymnastics; aerobic gymnastics; acrobatic gymnastics; trampolining; double mini trampoline, tumbling and parkour. Additionally, the federation is responsible for determining gymnasts' age eligibility to participate in the Olympics.
