Parliamentary elections were held in Mongolia on 22 June 1986.[1] At the time, the country was a one-party state under the rule of the Mongolian People's Revolutionary Party. The MPRP won 346 of the 370 seats, with the remaining 24 seats going to non-party candidates, who had been chosen by the MPRP due to their social status.[2] Voter turnout was reported to be 100%, with only ten of the 929,403 registered voters failing to cast a ballot.[3]
