List of Olympic Games host cities
Dette er en liste over værtsbyer for de olympiske lege og de olympiske ungdomslege, både sommer- og vinterlege, siden de moderne olympiske lege begyndte i 1896. Siden da har sommerlegene normalt - men ikke altid - været afholdt i en fireårig periode, der kaldes en olympiade. Der har været afholdt 28 olympiske sommerlege i 23 byer og 23 olympiske vinterlege i 20 byer. Derudover var der planlagt tre sommer- og to vinterudgaver af legene, som senere blev aflyst på grund af krig: Berlin (sommer) i 1916, Tokyo/Helsinki (sommer) og Sapporo/Garmisch-Partenkirchen (vinter) i 1940 samt London (sommer) og Cortina d'Ampezzo, Italien (vinter) i 1944. De olympiske sommerlege i 1906 blev officielt godkendt og afholdt i Athen. I 1949 besluttede Den Internationale Olympiske Komité (IOC) imidlertid at afvise at anerkende legene i 1906.  De olympiske ungdomslege afholdes hvert fjerde år med forskudte sommer- og vinterarrangementer i overensstemmelse med det nuværende format for de olympiske lege, dog i omvendt rækkefølge, idet vinterlegene afholdes i skudår i stedet for sommerlegene. Den første sommerudgave blev afholdt i Singapore fra den 14. til 26. august 2010, mens den første vinterudgave blev afholdt i Innsbruck, Østrig, fra den 13. til 22. januar 2012. Aldersgrænsen for atleterne er 14 til 18 år. Jacques Rogge, IOC-præsident, annoncerede formelt planerne for de olympiske ungdomssportlege på det 119. IOC-møde i Guatemala City den 6. juli 2007.  Der er flere mål for de olympiske ungdomslege, og fire af dem omfatter at samle verdens bedste unge atleter, at tilbyde en introduktion til olympisme, at være nyskabende inden for uddannelse og at debattere olympiske værdier.  Byen Singapore blev offentliggjort som vært for de første olympiske ungdomslege i sommer den 21. februar 2008.  Den 12. december 2008 meddelte IOC, at Innsbruck, der var vært for vinter-OL i 1964 og 1976, ville være vært for de første vinter-OL for unge i 2012.
IOC har udvalgt syv byer til at være værter for kommende olympiske lege og ungdoms-OL'er: Buenos Aires til sommer-OL for unge i 2018, Lausanne til vinter-OL for unge i 2020, Tokyo til sommer-OL i 2020, Beijing til vinter-OL i 2022, enten Abuja, Dakar, Gaborone eller Tunis til sommer-OL for unge i 2022, Paris til sommer-OL i 2024 og Los Angeles til sommer-OL i 2028.

List of Olympic Games host cities
This is a list of host cities of the Olympic Games and Youth 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.  The Youth Olympic Games  are held every four years in staggered summer and winter events consistent with the current Olympic Games format, though in reverse order with Winter Games held in leap years instead of Summer Games. The first summer version was held in Singapore from 14 to 26 August 2010 while the first winter version was held in Innsbruck, Austria from 13 to 22 January 2012. The age limitation of the athletes is 14 to 18. Jacques Rogge, IOC President, formally announced plans for the Youth Olympic Games at the 119th IOC session in Guatemala City on 6 July 2007.  There are several goals for the YOG, and four of them include bringing together the world's best young athletes, offering an introduction into Olympism, innovating in educating and debating Olympic values.  The city of Singapore was announced as the host of the inaugural Summer Youth Olympics on 21 February 2008.  On 12 December 2008 the IOC announced that Innsbruck, host of the 1964 and 1976 Winter Olympics, would be the host of the inaugural Winter Youth Olympics in 2012.
Seven cities have been chosen by the IOC to host upcoming Olympic Games and Youth Olympic Games: Buenos Aires for the 2018 Summer Youth Olympics, Lausanne for the 2020 Winter Youth Olympics, Tokyo for the 2020 Summer Olympics, Beijing for the 2022 Winter Olympics, either Abuja, Dakar, Gaborone or Tunis for the 2022 Summer Youth Olympics, Paris for the 2024 Summer Olympics, and Los Angeles for the 2028 Summer Olympics.
