[1][3] Kazakhstan returned home from Rio de Janeiro with 18 medals (three golds, five silver, and ten bronze), marking its most successful outcome in Summer Olympic history.

[4] As expected, most of the medals were distributed to the Kazakh athletes in both boxing and weightlifting, including a gold each from Youth Olympian Nijat Rahimov (men's 77 kg) and welterweight boxer Daniyar Yeleussinov.

[7] Apart from the winners, other medalists also included fellow boxers Niyazymbetov and Dychko, who managed to repeat their London 2012 feats in their respective weight divisions; Rypakova, who scored another medal with a bronze in the women's triple jump, bowing out of her title defense to Colombia's Caterine Ibargüen; Manyurova, who wrestled her way towards a runner-up finish in the women's 75 kg, adding a silver to her career hardware of three medals; and weightlifter Denis Ulanov, who received the bronze in the men's 85 kg, following the disqualification of Romania's Gabriel Sîncrăian over a doping offense.

The following is the list of number of competitors participating in the Games: Two Kazakh archers qualified each for both the men's and women's individual recurve by obtaining one of the three Olympic places available from the 2015 Asian Archery Championships in Bangkok, Thailand.

[17] The sprint canoeing squad, highlighted by London 2012 Olympians Natalya Sergeyeva and kayak duo of Yevgeniy Alexeyev and Alexey Dergunov, were officially named to the Kazakhstan roster on July 24, 2016.

[20] On July 30, 2016, Lutsenko withdrew from the Games due to a foot injury sustained from a car accident during his training in France, so his spot was awarded to a fellow cyclist Andrey Zeits.

[22] Kazakhstan has qualified one gymnast in the men's trampoline by picking up a spare berth freed by the Tripartite Commission, as the next highest from the eligible NOC on the individual ranking list at the 2016 Olympic Test Event in Rio de Janeiro.

[24][25] Being the highest-ranked judoka outside the world's top 22, Didar Khamza took over the vacant spot for Kazakhstan in the men's 73 kg, as Canada's Arthur Margelidon had been pulled out from the Games with a fractured forearm.

[27] Meanwhile, London 2012 Olympian Pavel Ilyashenko received a spare Olympic berth freed by one of the South Koreans, as the highest-ranked eligible modern pentathlete, not yet qualified, in the men's event at the same meet.

Kirill Gerassimenko scored a second-stage draw victory to book one of six remaining Olympic spots in the men's singles at the Asian Qualification Tournament in Hong Kong.

[37][38] Kazakh weightlifters have qualified a maximum of six men's and four women's quota places for the Rio Olympics based on their combined team standing by points at the 2014 and 2015 IWF World Championships.

On June 22, 2016, the International Weightlifting Federation had decided to strip one Olympic men's and one women's entry place each from Kazakhstan because of "multiple positive cases" of doping throughout the qualifying period.
