Kaisa Varis (born 21 September 1975, in Ilomantsi) is a retired Finnish cross country skier and biathlete. Her career has been marred by doping convictions: as a cross country skiier, she was involved but not suspended in a doping scandal and in 2003 she was suspended two years for doping use. After her suspension, she returned as a biathlete in 2007, but in 2008 she received a lifetime ban from all International Biathlon Union competitions after another positive doping test. However, her lifetime ban was overturned in March 2009 because the Court of Arbitration for Sport ruled that the IBU failed to adhere to correct testing procedures; she remains eligible to compete in biathlon.
