The Farm Workers Union of Småland (Swedish: Smålands lantarbetareförbund) was a trade union for agricultural workers in Småland, Sweden. The union was founded in 1919. The Farm Workers Union of Småland was connected to the Trade Union Propaganda League and the Social Democratic Left Party. The Social Democratic Left Party and the Social Democratic Youth League carried out agitations in Småland during 1919. As a result of the agitations, the Farm Workers Union of Småland was set up as an independent regional agricultural workers organization. Two men from Huskvarna shared the leadership of the union, Sven G. Lorén as chairman and Axel Tjäder as secretary. Lorén was also a member of the national party leadership and editor of Norra Småland.
