The 2010 Winter Olympics, officially known as the XXI Olympic Winter Games and commonly known as Vancouver 2010, informally the 21st Winter Olympics, were a major international multi-sport event held from February 12 to 28, 2010, in Vancouver, British Columbia, Canada, with some events held in the surrounding suburbs of Richmond, West Vancouver and the University Endowment Lands, and in the nearby resort town of Whistler. Approximately 2,600 athletes from 82 nations participated in 86 events in fifteen disciplines.
Both the Olympic and Paralympic Games were organized by the Vancouver Organizing Committee (VANOC), headed by John Furlong. The 2010 Winter Olympics were the third Olympics hosted by Canada and the first by the province of British Columbia. Previously, Canada hosted the 1976 Summer Olympics in Montreal, Quebec, and the 1988 Winter Olympics in Calgary, Alberta. Vancouver is the largest city to host the Winter Olympics.
