The 1928 Winter Olympics, officially known as the II Olympic Winter Games (French: Les IIes Jeux olympiques d'hiver; German: Olympische Winterspiele 1928; Italian: II Giochi olimpici invernali; Romansh: Gieus olimpics d'enviern 1928), was an international wintermulti-sport event that was celebrated from 11 to 19 February 1928 in St. Moritz, Switzerland.
The 1928 Games were the first true Winter Olympics to be held as a stand-alone event, not in conjunction with a Summer Olympics. The preceding 1924 Winter Games were retroactively renamed the inaugural Winter Olympics, although they had in fact been organised alongside the 1924 Summer Olympics in France. Before 1924, the winter events were included in the schedule of the Summer Games and there were no separate Winter Games. The 1928 Winter Games also replaced the now redundant Nordic Games, which had been held at varying intervals since early in the 20th century.
The hosts were challenged by fluctuating weather conditions; the opening ceremony was held in a blizzard, while warm weather conditions plagued sporting events throughout the rest of the Games. The 10,000 metre speed-skating event was controversially abandoned and officially cancelled.
Sonja Henie of Norway returned to the Winter Olympics, having taken part in 1924 at the age of 11, and made history by winning the ladies' figure skating aged 15. She became the youngest Olympic champion in history (a distinction she held for 70 years), and went on to defend her title at the next two Winter Olympics.
Norway's Ivar Ballangrud won the Olympic title in the 5,000-metre speed skating event, and Clas Thunberg of Finland won both the 500 m and the 1,500 m.
Norway finished at the top of the medal table with a total of six gold medals, four silver, and five bronze, totalling 15 medals. The United States finished second in the table with six medals overall.
Switzerland won a single bronze medal, the lowest medal haul by a host nation at any Olympic Games.
American Irving Jaffee was leading the 10,000-metre speed skating race, having outskated Norwegian defending world champion Bernt Evensen in their heat, when rising temperatures thawed the ice. In a controversial ruling, the Norwegian referee cancelled the entire competition; the International Olympic Committee stepped in to reverse the referee's decision and awarded Jaffee the gold medal, but the International Skating Union later overruled the IOC and restored the ruling. Evensen, for his part, stated publicly that Jaffee should be awarded the gold medal, but that did not happen.
