Parliamentary elections were held in the Mongolian People's Republic on 24 June 1973. At the time, the country was a one-party state under the rule of the Mongolian People's Revolutionary Party (MPRP). The MPRP won 282 of the 336 seats, with the remaining 54 seats going to non-party candidates, who had been chosen by the MPRP due to their social status. Voter turnout was reported to be 99.99%, with only 39 registered voters failing to cast a ballot.
