The only competing continent that has not hosted a Summer Olympics Games is Africa. There have been Olympics held in Europe, Asia, North America, South America, and Australia. There was also no African city that had hosted the FIFA World Cup until 2010, so a future African venue for the Olympics is not impossible.
The only continent not represented in the Olympics is Antarctica, which has only scientists as permanent residents, and is by treaty an international scientific preserve.
As of the 2008 Games, that would be Africa, South America, and Antarctica. Rio de Janeiro has been selected to host the 2016 Summer Games. That will be the first Olympics held in South America.
