Olga Nikolayevna Yegorova (Russian: Ольга Николаевна Егорова; born 28 March 1972 in Novocheboksarsk, Chuvash ASSR) is a Russian distance runner.

At the 2000 Summer Olympics she competed in 5000 metres, and she is a double world champion in this event, but like countryfellow Tatyana Tomashova she has concentrated on shorter races since, now competing mainly in the 1500 metres.

In 2001, she shared the $1 million jackpot of the IAAF Golden League and in the same year tested positive for EPO which drew protests from her fellow competitors after she was allowed to compete in the World Athletics Championships.

[2] Yegorova was one of seven Russian athletes to be suspended for doping offences ahead of the 2008 Beijing Olympics.

[3] On 20 October 2008, it was announced that Yegorova, along with 6 other Russian athletes, would receive two-year doping bans for manipulating drug samples.
