The 2018 Winter Olympics, officially known as the XXIII Olympic Winter Games (French: Les XXIIIes Jeux olympiques d'hiver; Korean: 제23회 동계 올림픽, romanized: Jeisipsamhoe Donggye Ollimpik) and commonly known as PyeongChang 2018, was an international winter multi-sport event that was held between 9 and 25 February 2018 in Pyeongchang County, Gangwon Province, South Korea, with the opening rounds for certain events held on 8 February 2018, the day before the opening ceremony.
Pyeongchang was elected as the host city in July 2011, at the 123rd IOC Session in Durban, South Africa. This was the second time that South Korea had hosted the Olympic Games, having previously hosted the 1988 Summer Olympics in Seoul, but it was only the first Winter Olympics to be held in the country. It was the first of three consecutive Olympics to be held in East Asia, the following two being Tokyo 2020 (summer) and Beijing 2022 (winter). It was the third time that an East Asian country had hosted the Winter Games, after Sapporo (1972) and Nagano (1998), both of these cities in Japan. It was also the first Winter Olympics to be held in mainland Asia.
The Games featured 102 events over 15 disciplines, a record number of events for the Winter Games. Four events made their Olympic debut in 2018: "big air" snowboarding, mass start speed skating, mixed doubles curling, and mixed team alpine skiing. A total of 2,914 athletes from 92 NOCs competed, including the national debuts of Ecuador, Eritrea, Kosovo, Malaysia, Nigeria and Singapore.
After a state-sponsored doping program was exposed following the 2014 Winter Olympics, the Russian Olympic Committee was suspended, but selected athletes were allowed to compete neutrally under the special IOC designation of "Olympic Athletes from Russia" (OAR). North Korea agreed to participate in the Games despite tense relations with South Korea; the two nations paraded together at the opening ceremony as a unified Korea, and fielded a unified team (COR) in the women's ice hockey.
Norway led the total medal tally with 39, followed by Germany's 31 and Canada's 29. Germany and Norway were tied for the highest number of gold medals, both winning 14. Host nation South Korea won 17 medals, their highest medal haul at a Winter Olympics, five of which were gold.
