The Olympic Oath is a solemn promise made by one athlete, judge or official, and one coach at the Opening Ceremony of each Olympic Games. Each oath taker is from the host nation and takes the oath on behalf of all athletes, officials, or coaches at the Games. The athletes' oath was first introduced for the 1920 Summer Olympic Games, with oaths for the officials and coaches added in 1972 and 2010. The oath is usually said in the language of the nation which is hosting the games; however, in 1994 both the athletes' and officials' oaths were said in English. Until the 1984 games the oath takers swore upon their nation's flag; since then all have taken the oath whilst holding the Olympic Flag. All three of the oaths were combined into one beginning at the 2018 Winter Games.

The Olympic Games ceremonies of the Ancient Olympic Games were an integral part of these Games; the modern Olympic games have opening, closing, and medal ceremonies. Some of the elements of the modern ceremonies date back to the Ancient Games from which the Modern Olympics draw their ancestry. An example of this is the prominence of Greece in both the opening and closing ceremonies. During the 2004 Games, the medal winners received a crown of olive branches, which was a direct reference to the Ancient Games, in which the victor's prize was an olive wreath. The various elements of the ceremonies are mandated by the Olympic Charter, and cannot be changed by the host nation. This requirement of seeking the approval of the International Olympic Committee (IOC) includes the artistic portion of opening and closing ceremonies.
