The Finnish Trade Union Federation (Finnish: Suomen Ammattijärjestö, SAJ) was a national trade union centre in Finland.
The federation was established in 1960, as a split from the Finnish Federation of Trade Unions (SAK), by unions which supported the Social Democratic Party of Finland.
By 1968, the federation had 17 affiliates, but a total of only 95,166 members.
In 1969, it merged with the SAK, to form the Central Organisation of Finnish Trade Unions.
