Nambaryn Enkhbayar (Mongolian: Намбарын Энхбаяр; born June 1, 1958 in Ulan Bator) is the current President of Mongolia. He took office on June 24, 2005 after winning the May 2005 elections. He was defeated for a second term by former Prime Minister Tsakhiagiin Elbegdorj in the 2009 presidental election. He is the first President of Mongolia to be defeated for reelection.

Enkhbayar is the ex-chairman of the former communist party - the Mongolian People's Revolutionary Party (MPRP). Enkhbayar was the Prime Minister of Mongolia from 2000 until 2004 and Speaker of Parliament between 2004 and 2005.

Born June 1, 1958 in Mongolia's capital city Ulan Bator, Nambaryn Enkhbayar graduated from secondary school in 1975 and went on to study at the Moscow Institute of Literature in 1980 where he earned an undergraduate degree in literature and language, and also attended English language courses at Leeds University in England in 1985 to 1986. It was in Britain that Enkhbayar encountered uncensored media for the first time and was particularly stunned by news coming out of the Soviet Union. Upon moving back to Ulan Bator, Enkhbayar worked for the Mongolian Writer's Union from 1980 to 1990 as a translator-editor, a secretary general and a vice president and he translated Buddhist teachings into Mongolian, and finally reached the top post at the Association of Mongolian Writers by 1990, the same year in which the Mongolian People's Revolutionary Party relinquished control and multiparty elections were held that July for the first time in Mongolian history. Enkhbayar, a MPRP member, became part of the new political order almost immediately, serving as a vice chair of a government arts committee for the first two years of democratic rule.
