The cross-country skiing events at the 2002 Winter Olympics were marred by drug problems. The winners of three races were disqualified after blood tests showed that three skiers had overly high red blood cell counts indicating the use of darbepoetin, a drug used to treat anemia. At the time, the drug was not specifically listed in the International Olympic Committee's (IOC) list of banned substances, but the Olympic rules generally prohibit doping of any kind, in accordance with its charter. After two years and several lawsuits in Olympic and Swiss courts, the skiers in question were stripped of all their medals from the 2002 Games.

The 2002 Winter Olympics, officially the XIX Olympic Winter Games and commonly known as Salt Lake 2002, was an international winter multi-sport event that was held from February 8 to 24, 2002, in and around Salt Lake City, Utah, United States.
