An Olympic Congress is a large gathering of representatives from the different constituencies of the Olympic Movement, organised by the International Olympic Committee (IOC). As detailed in chapter 1, rule 4 of the Olympic Charter, the IOC President is responsible for convening a Congress, presiding over its proceedings and for determining its procedures. Olympic Congresses are not regular events in the IOC’s calendar. As the Olympic Charter states, "The Olympic Congress gathers representatives of the constituents of the Olympic Movement, at intervals determined by the IOC".
