The 1948 Summer Olympics, officially the Games of the XIV Olympiad and officially branded as London 1948, were an international multi-sport event held from 29 July to 14 August 1948 in London, United Kingdom.

This was the second time London hosted the Olympic Games, having previously hosted them in 1908, making it the second city to host summer olympics twice. The Olympics would return again to London 64 years later in 2012, making London the first city to host the games thrice, and the only such city until Paris, who hosted their third games in 2024, and Los Angeles, who will host theirs in 2028. The 1948 Olympic Games were also the first of two summer Games held under the IOC presidency of Sigfrid Edström.
