Andriy Vasylovych Deryzemlya is a former Ukrainian biathlete who competed at the top level for eleven seasons before winning his first international medal, a bronze medal at the 2007 World Championship. In 2008 together with Oksana Khvostenko he won World Team Challenge.

The World Team Challenge is an international biathlon competition, which has been held every year between Christmas and New Year since 2002 in Veltins-Arena in Gelsenkirchen. Previously a similar competition was held at the same time of year in Ruhpolding, but since 2001 the venue was changed due to financial troubles. The competition isn't part of the World Cup.
