Olga Valeryevna Danilova (Russian: Ольга Валерьевна Данилова; born June 10, 1970 in Bugulma, Tatar ASSR) is a Russian cross country skier who competed from 1991 until she was banned for using performance-enhancing drugs in 2002. Her statistics are listed as:
- Height: 168 cm
- Weight: 56 kg
Danilova won a total of eleven medals at the FIS Nordic World Ski Championships, including four golds (4 x 5 km: 1995, 1997, 1999, 2001), four silvers (5 km: 1999, 10 km: 2001, 15 km: 2001, 30 km: 1999), and three bronzes (5 km + 10 km combined pursuit: 1995, 5 km: 1997, 5 km + 5 km combined pursuit: 2001). She also won the 30 km event at the Holmenkollen ski festival in 2000.
In 2002, she again participated in the cross country skiing events at the 2002 Winter Olympics. Danilova won two medals with a gold in the 5 km + 5 km combined pursuit and a silver in the 10 km classical. However, she was one of three cross-country skiers (together with Johann Mühlegg and Larisa Lazutina) who was disqualified after blood tests indicated the use of darbepoetin, a drug intended to boost red blood cell production.
In February 2004 the I.O.C. stripped Danilova's medal awards following a Court of Arbitration for Sport (CAS) ruling in December, 2003. The results were amended accordingly. As a result of the use of the banned substance, Olga Danilova received a two-year ban by the International Ski Federation in 2002.
