The National Federation of Agricultural Workers (French: Federation nationale des travailleurs de l'agriculture, FNTA) was a trade union representing agricultural and forestry workers in France.
An Agriculture and Horticulture Federation was formed in 1903, but ceased to operate during World War I.
The National Federation of Loggers' Unions of France and the Colonies was founded in 1902, and survived the war.
It regularly took part in merger discussions with the Agriculture and Horticulture Federation, but these were unsuccessful.
On founding, it had 198 local sections, and membership grew rapidly, reaching 30,000 by the end of the year.
