International Yo-Yo Federation (IYYF) is a global nonprofit organization dedicated to developing and promoting yo-yoing as a sport. Their mission is to improve yo-yoing on a competitive level, unite national associations, and advance the sport's goals. Their primary objectives include enhancing the competitive scene to motivate current players and attract new ones, establishing national associations and unions globally, organizing national contests, and supporting local communities.

They also aim to improve the presentation of contests, unify rules and judging systems to entertain the public, and attract new fans, sponsors, and media worldwide. IYYF organizes and supports competitions and activities of global significance, while also assisting yo-yo companies in designing innovative products, building their brand, and entering new markets. They believe that yo-yoing is a sport that should promote fair-play, sportsmanship, and tolerance.

All people are encouraged to join the yo-yo community and enjoy the sport regardless of gender, ethnic background, faith, or culture
