The 1906 Intercalated Games or 1906 Olympic Games was an international multi-sport event that was celebrated in Athens, Greece. They were at the time considered to be Olympic Games and were referred to as the "Second International Olympic Games in Athens" by the International Olympic Committee. However, the medals that were distributed to the participants during these games are not officially recognised by the Olympic Committee and are not displayed with the collection of Olympic medals at the Olympic Museum in Lausanne, Switzerland.

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.
