The 29th modern summer Olympic Games took place in Beijing, China until August 24.

The 2008 Summer Olympics, officially the Games of the XXIX Olympiad and officially branded as Beijing 2008, were an international multi-sport event held from 8 to 24 August 2008, in Beijing, China. A total of 10,942 athletes from 204 National Olympic Committees (NOCs) competed in 28 sports and 302 events, one event more than those scheduled for the 2004 Summer Olympics. This was the first time China had hosted the Olympic Games, and the third time the Summer Olympic Games had been held in East Asia, following the 1964 Olympics in Tokyo, Japan, and the 1988 Olympics in Seoul, South Korea. These were also the second Summer Olympic Games to be held in a communist state, the first being the 1980 Summer Olympics in the Soviet Union. The games were the first and only Olympics held in Beijing with spectators, as the 2022 Winter Games were held without spectators due to the COVID-19 pandemic. By hosting the 2022 Winter Olympics, Beijing became the first ever city to host both the Summer and Winter Games.
