The Chairman of the Democratic Party () is the leader of the Democratic Party, established on 6 December 2000 when five opposition parties merged. The party traces its historic roots back to the 1990 Democratic Revolution, when the Mongolian Democratic Party was founded by the Mongolian Democratic Union.
The chairperson of the DP is elected by a direct majority vote by the party presidium, the National Policy Committee (NPC). The current chairperson is Odongiin Tsogtgerel, who was elected to the position in 2025.
Between late 2020 and 2023, the party's leadership was disputed between various factions. Officially, however, Sodnomzunduin Erdene remained as the registered party chairman by the Supreme Court until 2023, when he was succeeded by Luvsannyamyn Gantömör, who was elected by the NPC with 152 votes.
