The Finnish Police Federation (Finnish: Suomen Poliisijärjestöjen Liitto, SPJL) is a trade union representing police and associated workers in Finland. The union was founded in 1923. in 1945 it affiliated to the Finnish Federation of Trade Unions (SAK), but it left in 1956. In 1969, it joined the SAK's successor, the Central Organisation of Finnish Trade Unions. By 1984, it was unhappy with the federation's links to the Social Democratic Party, so it transferred to the Confederation of Salaried Employees (TVK). By 1992, it had grown to 12,940 members. However, that year the TVK went bankrupt, and the union transferred to the Finnish Confederation of Professionals (STTK).
