The International Naturist Federation (INF) or Fédération naturiste internationale (FNI) or Internationalen Naturisten Föderation (INF) is the global umbrella organisation representing official national naturist societies.

Membership
The INF is made up of representatives of national naturist organisations. The rules of the federation limit membership to one national society. To by-pass this rule, the French and English-speaking Canadian societies formed a partnership for the purpose of participating in the INF.

Some federations have independent youth organisations which are currently not affiliated to the INF directly. On European level, youth representatives (European Naturist Youth – ENY) have elected a Youth committee to speak towards the INF and the European Naturist Assembly (EuNat). Its task is to coordinate events and promote communication and exchange between young naturists.

The rules of INF provide for direct membership in the INF if there is no affiliated national naturist organisation in the country of residence.
