The Juche Idea; sometimes spelled Chuch'e (Korean pronunciation: [t?ut??e]) is a political thesis of Kim Il-sung; the founder of the Democratic People's Republic of Korea; which says that the Korean masses are the masters of the country's development.

From the 1950s to the 1970s; Kim elaborated the Juche Idea into a set of principles that the government uses to justify its policy decisions. Among these are a strong military posture and reliance on Korean national resources. The name comes from juche; meaning 'main body' or 'mainstream'; and is sometimes translated in North Korean sources as 'independent stand' or 'spirit of self-reliance'.

It has also been interpreted as 'always putting Korean things first'. According to Kim Il-sung; the Juche Idea is based on the belief that 'man is the master of everything and decides everything'.
