The Union of Soviet Socialist Republics (USSR) first participated at the Olympic Games in 1952, and competed at the Summer and Winter Games on 18 occasions subsequently. At six of its nine appearances at the Summer Olympic Games, the Soviet team ranked first in the total number of gold medals won, second three times, and became the biggest contender to the United States' domination in the Summer Games. Similarly, the team was ranked first in the gold medal count seven times and second twice in its nine appearances at the Winter Olympic Games. The Soviet Union's success might be attributed to a heavy state investment in sports to fulfill its political objectives on an international stage.

The Summer Olympic Games, also known as the Games of the Olympiad, and often referred to as the Summer Olympics, is a major international multi-sport event normally held once every four years on leap years. The inaugural Games took place in 1896 in Athens, Greece, and the most recent Games were held in 2021 in Tokyo, Japan. The International Olympic Committee (IOC) is responsible for organising the Games and for overseeing the host city's preparations. The tradition of awarding medals began in 1904; in each Olympic event, gold medals are awarded for first place, silver medals for second place, and bronze medals for third place.The Winter Olympic Games were created out of the success of the Summer Olympic Games, which are regarded as the largest and most prestigious multi-sport international event in the world.
