Polina Sergeyevna Frolova, née Malchikova (Russian: Полина Сергеевна Фролова; born 1 March 1986) is a Russian ski-orienteering competitor, who was suspended for four years for doping.
She won a gold medal in the middle distance at the 2011 World Ski Orienteering Championships in Sweden, ahead of Alena Trapeznikova and Stine Olsen Kirkevik.[1] In 2017, Frolova was found guilty of doping and therefore stripped of all medals won in 2017 and banned from competing for 4 years.[2]
