International Federation of American Football (IFAF) is the international governing body of American football associations. Its headquarters are in La Courneuve, France, and its current president is Tommy Wiking. The IFAF oversees the IFAF World Championship of American Football, which is held every four years.

The first national American Football federation outside of the United States was founded in Canada in 1896, as Canada already had a long history with Canadian football. Japan was also an early adopter of American football, establishing its national federation in 1936. The first European federation was formed in 1976. Since then, the sport has experienced a significant expansion, especially in Europe, culminating in the founding of the European Federation of American Football in 1996. Two years later (1998), the International Federation of American Football was officially formed. The IFAF became a provisionary member of the General Association of International Sports Federations in 2003, and became a full GAISF member in 2005.
