The Olympic Movement encompasses all organisations involved in the Olympic Games. The rules and guidelines by which these organisations operate are outlined in the Olympic Charter.

At the heart of the Olympic Movement is the International Olympic Committee (IOC). It can be seen as the government of the Olympics, as it takes care of the daily problems and takes all important decisions, such as the host city of the Games and the programme of the Olympics.

Three groups of organisations operate on a more specialised level: International Federations (IFs), the governing bodies of a sport (e.g. FIFA)
National Olympic Committees (NOCs), which regulates the Olympic Movement within one country (e.g. USOC)
Organising Committees for the Olympic Games (OCOGs), which take care of the organisation of a specific celebration of the Olympics.
At present, 202 NOCs and 35 IFs are part of the Olympic Movement.
