Presidential elections were held in Mongolia on 26 June 2017. Incumbent President Tsakhiagiin Elbegdorj, first elected in 2009 and re-elected in 2013, was constitutionally barred from running for a third term. For the first time, no candidate received a majority of the vote in the first round, forcing a run-off between Khaltmaagiin Battulga and Miyeegombyn Enkhbold on 7 July, brought forward from 9 July. The third-placed candidate Sainkhuugiin Ganbaatar refused to recognise the results after he missed out on the second round due to finishing 1,849 behind Enkhbold, claiming that an additional 35,000 votes had been added to the total and there had been fraud. His Mongolian People's Revolutionary Party demanded a recount of votes in Bayan-Ölgii.

Khaltmaagiin Battulga is a Mongolian politician and sambo wrestler who served as the 5th President of Mongolia from 2017 to 2021. He served as Member of the State Great Khural from 2004 to 2016 and Minister of Roads, Transportation, Construction and Urban Development from 2008 to 2012. Before his career in politics, Battulga was a sambo wrestling champion. He was the Democratic Party's candidate in the 2017 presidential election and was elected President with 50.6% in the run-off, the first-ever run-off election in modern Mongolian history. Mongolians are divided about his role in the 2019 Mongolian constitutional crisis.
