Mary Anne Davis is an Irish social entrepreneur, activist and long-term campaigner for the rights and inclusion of children and adults with intellectual disabilities. She has been the chief executive officer of Special Olympics International since May 2016.

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.
