The Olympic Charter is a set of rules and guidelines for the organisation of the Olympic Games, and for governing the Olympic movement. Its last revision was on the 17th of July 2020 during the 136th IOC Session, held by video conference. Adopted by the International Olympic Committee (IOC), it is the codification of the fundamental principles, rules and by-laws. French and English are the official languages of the Olympic Charter.

The modern Olympic Games or Olympics are the leading international sporting events featuring summer and winter sports competitions in which thousands of athletes from around the world participate in a variety of competitions. The Olympic Games are considered the world's foremost sports competition with more than 200 teams, representing sovereign states and territories participating; by default the Games generally substitute for any World Championships the year in which they take place. The Olympic Games are held every four years; since 1994, they have been alternated between the Summer and Winter Olympics every two years during the four-year period.
