Nadzeya Astapchuk 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.
