The Organization of African Trade Union Unity (OATUU) is an independent regional union federation for trade union centres in Africa.

Founded in 1973 (under the Organization of African Unity), from the merger of the All-African Trade Union Federation (AATUF), the African Trade Union Confederation (ATUC), and the smaller Pan-African Workers’ Congress, the OATUU has maintained a position of independence from the International union federations.

The OATUU has four regional organizations an 73 affiliates.
Its aims is to build trade union unity at both continental and national levels and to co-ordinate and guide the actions of the affiliated trade unions, to defend trade union freedom and the material, cultural and moral interests of the African working class and enhance the policy of full employment and equitable distribution of national income, to work for the harmonization of labour legislation and collective bargaining in member countries and to assist all trade unions especially those in countries still under colonial and foreign domination to accelerate the total liberation of the African continent
