Mongolia has qualified a total of nine wrestlers for each of the following weight classes into the Olympic tournament. Five Olympic berths were awarded to Mongolian wrestlers, who finished among the top six at the
2015 World Championships, while the other half of the wrestling roster had booked Olympic spots by progressing to the top two finals at the
2016 Asian Qualification Tournament. One further wrestler had claimed the remaining Olympic slot in the men's freestyle 97 kg to round out the Mongolian roster at the
final meet of the World Qualification Tournament in
Istanbul. On 11 May 2016,
United World Wrestling decided to revoke an Olympic license from Mongolia in women's freestyle 53 kg, due to doping violations at the Asian Qualification Tournament, but the license was reinstated two months later, following the recent
meldonium guidelines released by IOC and WADA. ;Men's freestyle ;Women's freestyle ==See also==
