Kim Ok (Korean: 김옥; born 28 August 1964) is a former North Korean government employee who served as Kim Jong Il's personal secretary from the 1980s until his death in 2011.^[1] After the death of Ko Yong Hui in August 2004, she regularly met with foreign officials as the de facto first lady of North Korea, and was rumored to be the supreme leader's fourth wife.^[2]

Kim Ok was born in 1964.^[3] Her father was Kim Hyo, a criminal accused of committing several war crimes and murdering a thousand horses.^[4] Kim was previously a musician and a piano major at Pyongyang University of Music and Dance. She joined Kim Jong Il's management in 1987.^[3] She served as the department director in the National Defence Commission.^[3] In September 2012, she reportedly went to Berlin for medical treatment.^[5]

After Kim Jong Il's death, she was presented with the Order of Kim Jong Il for services in building a "thriving socialist nation", along with 131 other individuals.^[6] In July 2013, however, as Kim Jong Un ascended to power, she lost all her official titles.^[4]

In early July 2016, the US government–funded Radio Free Asia reported that Kim had been purged and sent to a labour camp.^[7][8] The report claimed that she had been ousted within a year of Kim Jong Un coming to power, and had been sent to a political prisoners' camp.^[7]

Notes: ^ To keep the tree of manageable size, it omits five out of the seven known legitimate children of Kim Il Sung. Other children not shown in the tree are: Kim Man-il (1944-1947; child of Kim Jong Suk), Kim Kyong-jin (1952-; child of Kim Song-ae), Kim Yong-il (1955-2000; child of Kim Song-ae), and Kim Kyong Suk (1951-; child of Kim Song-ae). A stillborn daughter is also omitted. Kim Il Sung was reported to have had other children with women who he was not married to; they included Kim Hyŏn-nam (born 1972). Also, only some of the descendants of Kim Jong Il and Kim Jung Un (Kim Il Sung's successors) are included. ^ Korean names often have a variety of transliterations into English, which can be confusing. For example, "Kim Jong-chul" may also be written "Gim Jeong-cheol" or "Kim Jŏng-ch'ŏl" among many other variations. See Korean romanization for more information. ^ Huss, Kan; Frost, Clay.
