The biathlon competition at the 2010 Winter Olympics were held at Whistler Olympic Park in Whistler, British Columbia. The events were held between the 13th and 26 February 2010.
The men's individual biathlon was notable for the awarding of two silver medals due to two competitors finishing with a tie (48:32.0). No bronze medal was awarded in this event.
In October 2020, the medals won by Evgeny Ustyugov in 2010 were revoked as a result of new tests for doping violations. In November 2024, almost 15 years after the Vancouver Olympic Games, the CAS rejected Ustyugov's appeal for the deprivation of his Olympic medals. In May 2025, the Swiss Federal Tribunal rejected the appeals of Ustyugov, leaving the International Olympic Committee to formally reallocate Ustyugov's medals to other athletes. In September 2025 the IOC Executive Board approved the medal reallocations.
