The 1920 Summer Olympics (French: Les Jeux olympiques d'été de 1920), officially known as the Games of the VII Olympiad, were an international multi-sport event in 1920 in Antwerp, Belgium. In March 1912, during the 13th session of the IOC, the bid on the behalf of Belgium to host the 1920 Summer Olympics was made by Baron Édouard de Laveleye, president of the Belgian Olympic Committee and of the Royal Belgian Football Association. No fixed host city was proposed at the time.

The 1916 Summer Olympics, to be held in Berlin, capital of the German Empire, were cancelled due to World War I. The aftermath of the war and the Paris Peace Conference, 1919 affected the Olympic Games not only due to new states being created, but also by sanctions against the nations that lost the war and were blamed for starting it. Hungary, Germany, Austria, Bulgaria, and the Ottoman Empire were banned from competing in the Games. Germany did not return to Olympic competition until 1928 and instead hosted a series of games called Deutsche Kampfspiele, starting with the Winter edition of 1922 (which predated the first Winter Olympics).

The Sailing events were held in Ostend, Belgium, and two in Amsterdam, Netherlands.
