,Latin-American labour union federation that was established in 1951 as a regional organization for the Latin-American members of the International Confederation of Free Trade Unions, which had been founded in 1949 primarily by the American Federation of Labor–Congress of Industrial Organizations (AFL–CIO) of the United States and the Trades Union Congress of Great Britain. At the time of ORIT's founding, the bulk of its members comprised most of the union groups formerly affiliated with the Inter-American Confederation of Workers (Confederación Interamericana de Trabajadores), a democratic, anticommunist organization that had been subjected to political attacks for its strong U.S. orientation.

The aims of the new organization included land reform, opposition to totalitarianism, and support for organizing efforts in areas where unionism was weak. One of its well-known activities, which began in the 1950s, was the sponsorship of a training school for trade-union leaders.
