Tatyana Nikolayevna Andrianova (Russian: Татьяна Николаевна Андрианова, born 10 December 1979 in Yaroslavl) is a Russian former middle-distance runner who specialized in the 800 metres.

In the 2004 Olympics in Athens, Andrianova was fifth in the final,[1] so in the 2005 World Championships she was a favourite.

“I was already planning to get married and give birth to my child, and I was not sure I would be back on the track again.

[1] The IAAF reported in December 2015 that Andrianova would be retroactively suspended for testing positive for the performance-enhancing drug stanozolol.

[4][5] On 14 April 2016 the Court of Arbitration for Sport (CAS) has overturned an Andrianova's two-year doping suspension because her sample was retested beyond the eight-year statute of limitations.
