Special Olympics USA is a sports organization for children and adults with intellectual disabilities in the United States. It is part of the global Special Olympics movement. Special Olympics was founded in 1968 with the main goal of accepting and welcoming individuals as they are. Special Olympics provides year-round training in Olympic based sports and is based in 204 countries.

Special Olympics is the world's largest sports organization for children and adults with intellectual disabilities providing year-round training and activities to 5 million participants and Unified Sports partners in 172 countries. Special Olympics competitions are held daily, all around the world—including local, national and regional competitions, adding up to more than 100,000 events a year. Like the International Paralympic Committee, the Special Olympics organization is recognized by the International Olympic Committee; however, unlike the Paralympic Games, its World Games are not held in the same year nor in conjunction with the Olympic Games.
