Medal relocations after positive dopping tests.
1. Men 4×100 metres relay: Tyson Gay was stripped of his silver medal due to doping violations. Following consideration by the IOC, the United States team was disqualified. The decision was referred back to the IAAF for other results to be adjusted in the wake of the disqualification, promoting Trinidad and Tobago to silver, and France to bronze. The French team received their bronze medals at the IAAF Diamond League in Paris in July 2015.
2. Men 50km Walk: On 24 March 2016, the Court of Arbitration for Sport has issued decision that all competitive results obtained by Sergey Kirdyapkin of Russia from 20 August 2009 to 15 October 2012 are disqualified. Redistribution of the medals in this event occurred in 17 June 2016, with Tallent awarded the gold medal by the IOC at a ceremony in Melbourne, Australia,[12] with Si claiming silver and Heffernan bronze.
3. Men Javelin Throw: Original silver medalist Oleksandr Pyatnytsya of Ukraine was stripped of his silver medal and result following a positive finding in a retest of his 2012 anti-doping sample. On 24 February 2017 Antti Ruuskanen received the silver medal in Finland. On 28 June 2017 VÃtÄ›zslav Veselý received the bronze medal in Czechia.

Medal relocations after positive dopping tests.
1. Women 800m: On 10 February 2017, the Court of Arbitration for Sport upheld a four-year ban that effectively stripped of the gold medal of Mariya Savinova, based upon her biological passport. Caster Semenya of South Africa was advanced to gold, and Ekaterina Poistogova of Russia to silver. In the case of bronze medal reallocation the bronze medal will be awarded to Pamela Jelimo of Kenya.
2. Women 1500m: On 17 August 2015, the Court of Arbitration for Sport says it approved a settlement agreed to by Turkish athlete Aslı Çakır Alptekin and the IAAF. Alptekin has agreed to forfeit her 1500 metres Olympic title and serve an eight-year ban for blood doping. On 29 March 2017, Turkish athlete Gamze Bulut was banned for doping and lost her Olympic silver medal. Maryam Yusuf Jamal of Bahrain was advanced to gold. In the case of silver and bronze medals reallocation the silver medal could be awarded to Tatyana Tomashova of Russia, and the bronze medal could be awarded to Abeba Aregawi of Ethiopia. However when reallocating medals, the IOC has previously elected not to advance athletes with a history of doping violations. Both Tatyana Tomashova and Abeba Aregawi had doping violations in the past. Therefore, it is possible that runners from the United States (Shannon Rowbury) and Slovakia (Lucia Klocová) in the original sixth and seventh positions could be awarded medals.
3. Women 3000m Steeplechase: On 30 January 2015, the Russian Anti-Doping Agency confirmed that runner Yuliya Zaripova will be stripped of her gold medal in the 3,000 metres steeplechase after testing positive for anabolic steroids. On 4 June 2016, the gold medal was officially reallocated to second place Habiba Ghribi from Tunisia by the IOC and IAAF updated the results.
4. Women 4x400 Relay: On 1 February 2017, the International Olympic Committee stripped the silver medal of the Russian team due to doping of Antonina Krivoshapka Medals were reallocated.
5. Women 20km Walk: On 24 March 2016, the Court of Arbitration for Sport has issued decision that all competitive results obtained by Olga Kaniskina from 15 August 2009 to 15 October 2012 are disqualified. Qieyang Shenjie of China was advanced to silver, and Liu Hong of China to bronze.
6. Women Shot Put: The original winner, Nadzeya Ostapchuk of Belarus, was stripped of her gold medal shortly after the event after failing a doping test. The rest of the competitors were elevated by one position accordingly. On 20 August 2016, Yevgeniya Kolodko of Russia was also stripped of her silver medal after retested samples from the competition returned a positive doping result. Gong Lijiao of China was advanced to silver, and Li Ling of China to bronze.
7. Women Discus Throw: The original silver medalist, Darya Pishchalnikova of Russia, was stripped of her silver medal after failing drugs tests. The rest of the competitors were elevated by one position accordingly.

Doping: Prior to the Olympic competition, several prominent athletes were ruled out of the competition due to failed tests. World indoor medallists Dimitrios Chondrokoukis, Debbie Dunn, and Mariem Alaoui Selsouli were withdrawn from their Olympic teams in July for doping, as was 2004 Olympic medallist Zoltán Kővágó.
At the Olympic competition, Tameka Williams admitted to taking a banned stimulant and was removed from the games.
Ivan Tsikhan did not compete in the hammer throw as a re-test of his sample from the 2004 Athens Olympics, where he won silver, was positive.
Hassan Hirt, Amine Laâlou, Marina Marghieva, Diego Palomeque and defending 50km walk champion Alex Schwazer were also suspended before taking part in their events.
Syrian hurdler Ghfran Almouhamad became the first track-and-field athlete to be suspended following a positive in-competition doping sample.
Nadzeya Astapchuk was stripped of the women's shot put title after her sample came back positive for the banned anabolic agent metenolone.
Karin Melis Mey was withdrawn before the long jump final when an earlier failed doping test was confirmed.
Multiple medalists were found guilty of doping after the Olympics. Russia has the most (9) medals stripped.
