<P> This is a list of host cities of the Olympic Games, both summer and winter, since the modern Olympics began in 1896 . Since then, summer games have usually--but not always--celebrated a four - year period known as an Olympiad . There have been 28 Summer Olympic Games held in 23 cities, and 23 Winter Olympic Games held in 20 cities . In addition, three summer and two winter editions of the Games were scheduled to take place but later cancelled due to war: Berlin (summer) in 1916; Tokyo / Helsinki (summer) and Sapporo / Garmisch - Partenkirchen (winter) in 1940; and London (summer) and Cortina d'Ampezzo, Italy (winter) in 1944 . The 1906 Summer Olympics were officially sanctioned and held in Athens . However, in 1949, the International Olympic Committee (IOC), decided to unrecognize the 1906 Games . Four cities have been chosen by the IOC to host upcoming Olympic Games: Tokyo for the 2020 Summer Olympics, Beijing for the 2022 Winter Olympics, Paris for the 2024 Summer Olympics, and Los Angeles for the 2028 Summer Olympics . </P> <P> In 2022, Beijing will become the only city that has held both the summer and the winter Olympic Games . Nine cities will have hosted the Olympic Games more than once: Athens (1896 and 2004 Summer Olympics), Paris (1900, 1924 and 2024 Summer Olympics), London (1908, 1948 and 2012 Summer Olympics), St. Moritz (1928 and 1948 Winter Olympics), Lake Placid (1932 and 1980 Winter Olympics), Los Angeles (1932, 1984 and 2028 Summer Olympics), Innsbruck (1964 and 1976 Winter Olympics), Tokyo (1964 and 2020 Summer Olympics) and Beijing (2008 Summer Olympics and 2022 Winter Olympics). In addition, Stockholm hosted the 1912 Summer Olympics and the equestrian portion of the 1956 Summer Olympics . London became the first city to have hosted three Games with the 2012 Summer Olympics . Paris will become the second city to do this with the 2024 Summer Olympics, followed by Los Angeles as the third in 2028 . The United States has hosted a total of eight Olympic Games, more than any other country, followed by France with five editions . Canada, Germany, Italy, Japan, and the United Kingdom have each hosted three Games . </P> <P> The Games have primarily been hosted in the continents of Europe (36 editions) and North America (12 editions); eight Games have been hosted in Asia and two have been hosted in Oceania . In 2016, Rio de Janeiro became South America's first Olympic host city, while the African continent has yet to hold the Games . Other major geographic regions which have never hosted the Olympics include the Middle East, the Indian subcontinent, the Caribbean, and Southeast Asia . </P>
