Kim Jong-un(English: /ˌkɪm dʒɒŋˈʊn, -ˈuːn/; Korean: 김정은, Korean: [kim.dʑɔŋ.ɯːn]; born 8 January 1982) is a North Korean politician who has been Supreme Leader of North Korea since 2011 and the leader of the Workers' Party of Korea (WPK) since 2012. He is a son of Kim Jong-il, who was North Korea's second supreme leader from 1994 to 2011, and Ko Yong-hui. He is a grandson of Kim Il-sung (who was the founder and first supreme leader of North Korea from its establishment in 1948 until his death in 1994) and the first leader of North Korea to have been born in the country after its founding in 1948.

From late 2010, Kim was viewed as successor to the leadership of North Korea. Following his father's death in December 2011, state television announced Kim as the "Great Successor". Kim holds the titles of General Secretary of the Workers' Party of Korea, Chairman of the Central Military Commission, and President of the State Affairs.
