The Federation of Printing Workers of Luxembourg (French: Fédération luxembourgeoise des travailleurs du livre, FLTL) was a trade union representing workers in the printing and paper industries in Luxembourg.
It was founded on 31 July 1864, as the Typographical Association, on the initiative of Peter Klein.
The strongest 19th-century trade union in the country, it achieved significant improvements in working conditions for its members.
It began admitting all workers in the printing and paper industries in 1945, and accordingly changed its name to the FLTL, but remained small, with only 400 members in 1965.
On 9 December 2005, it merged into the Independent Luxembourg Trade Union Confederation.
