This is a list of federations of trade unions currently in existence. Those federations listed under each country are also known as national trade union centres and are organizations formed by trade unions which operate, in most cases, at the national level. The organizations listed in the worldwide section are industry/sectoral-specific (i.e. the GUFs) and international organizations representing national trade union centres (e.g. ITUC).
The Council of Global Unions (CGU) is made up of ten global union federations (which affiliates national-level sectoral trade unions), the largest international federation of national centres (the ITUC) and the trade union body to the OECD (TUAC).
