Kim Jong-chul (born 25 September 1981), sometimes spelled Kim Jong Chol, is a son of former North Korean Supreme Leader Kim Jong-il.
His younger brother is Kim Jong-un, now the leader of North Korea.
His older half-brother was Kim Jong-nam, who was assassinated in February 2017.
In 2007, Jong-chul was appointed deputy chief of a leadership division of the Workers' Party of Korea.
However, on 15 January 2009, the South Korean Yonhap News Agency reported that Kim Jong-il appointed his youngest son, Jong-un, to be his successor, passing over Jong-nam and Jong-chul.
These reports were supported in April 2009 when Kim Jong-un assumed a low-level position within the ruling Workers' Party, since Kim Jong-il was groomed by his own father, Kim Il-sung, in a similar way before becoming North Korean leader in 1994.
