Union des sociétés françaises de sports athlétiques (USFSA) is a former French sports governing body. During the 1890s and early 1900s it organised numerous sports including athletics, cycling, field hockey, fencing, croquet and swimming. However it is perhaps best known for being the principal governing body of both football and rugby union in France until it was effectively replaced by the French Football Federation and the French Rugby Federation. The USFSA rejected any form of professionalism and were strong advocates of amateur sport.
