Nadezhda Ostapchuk

Nadzeya Astapchuk (Belarusian: Надзея Мікалаеўна Астапчук, Nadzeya Mikalayeuna Astapchuk; Russian: Надежда Остапчук, Nadezhda Ostapchuk; born October 28, 1980) is a Belarusian shot putter. She briefly was designated the Olympic Champion in 2012, but was subsequently stripped of the title for failing a drug test and the gold medal was awarded to New Zealand shot putter Valerie Adams. She was World Champion in 2005, but in March 2013, the IAAF reported that her drug test sample from that event had been retested and found to be positive.

Astapchuk was initially designated as the bronze medallist at the 2008 Beijing Olympics (but was subsequently disqualified from that too, because of a doping violation), and was the World Indoor and European Champion in 2010. Her overall personal best of 21.70 m that year is the fourth best women's all-time distance indoors. However, IAAF has subsequently disqualified all of her results since August 2005.

She is a four-time runner-up at the World Indoor Championships and a three-time World Championships silver medallist outdoors. She holds the Championship record for the former event, with her winning throw of 20.85 m in 2010. In continental competition, she was the 2005 European Indoor champion and came second at the 2006 European Athletics Championships. In addition to her withdrawn medals in Beijing and London, she was fourth at the 2004 Athens Olympics before the disqualification of Svetlana Krivelyova. Though upgraded to third place in Athens, the IOC declined to award her a bronze medal.
