The Social Democratic Federation of the United States of America (SDF) was a political party in the United States, formed in 1936 by the so-called "Old Guard" faction of the Socialist Party of America. The SDF later merged again with the Socialist Party in 1957 to form the Socialist Party-Social Democratic Federation (SP-SDF).[1]
