Yuliya Sergeyevna Pechonkina, née Nosova (Russian: Юлия Серге́евна Печёнкина, born 21 April 1978 in Krasnoyarsk) is a Russian former athlete who specialized in the 400 metres hurdles and 4 × 400 metres relay.

[1] She held the world record in 400 m hurdles (52.34 seconds achieved on 8 August 2003 in Tula) for almost 16 years until it was broken by Dalilah Muhammad on 28 July 2019 and the rarely contested 4 × 200 metres relay indoor (1:32.41 with Yekaterina Kondratyeva, Irina Khabarova and Yuliya Gushchina).

She had a recurring problem with sinusitis, an illness which caused her to miss both the 2008 Beijing Olympics and the 2009 World Championships in Berlin.

[2] Given her ill health, she decided to retire from athletics soon after the World Championships and instead took a job in the banking sector.

[3] She has an annual meet held in Yerino named after her, under the title Yuliya Pechonkina Prizes.
