The Olympic Games are an international multi-sport event featuring both summer and winter sports, held every two years with Summer and Winter Olympic Games alternating. During Olympic Games opening ceremonies, the sitting president of the International Olympic Committee (IOC) will make a speech before inviting a representative from the host country to officially declare that particular Games open.

This article lists the people who have had the ceremonial duty to declare each Olympic Games open.
