National Olympic Committees that wish to host an Olympic Games select cities within their territories to put forth bids for the Olympic Games. The staging of the Paralympic Games is automatically included in the bid. Since the creation of the International Olympic Committee (IOC) in 1894, which successfully appropriated the name of the Ancient Greek Olympics to create a modern sporting event, interested cities have rivaled for selection as host of the Summer or Winter Olympic Games. 51 different cities have been chosen to host the modern Olympics: three in Eastern Europe, five in East Asia, one in South America, three in Oceania, nine in North America and all the others in Western Europe. No Central American, African, Central Asian, Middle Eastern, South Asian, or Southeast Asian city has ever been chosen to host an Olympics.

The ancient Olympic Games were a series of athletic competitions among representatives of city-states and one of the Panhellenic Games of Ancient Greece. They were held at the Panhellenic religious sanctuary of Olympia, in honor of Zeus, and the Greeks gave them a mythological origin. The originating Olympic Games are traditionally dated to 776 BC. The games were held every four years, or Olympiad, which became a unit of time in historical chronologies. These Olympiads were referred to based on the winner of their stadion sprint, e.g., "the third year of the eighteenth Olympiad when Ladas of Argos won the stadion". They continued to be celebrated when Greece came under Roman rule in the 2nd century BC. Their last recorded celebration was in AD 393, under the emperor Theodosius I, but archaeological evidence indicates that some games were still held after this date. The games likely came to an end under Theodosius II, possibly in connection with a fire that burned down the temple of the Olympian Zeus during his reign.
