The politics of North Korea takes place within the framework of the official state philosophy, Kimilsungism-Kimjongilism. Juche, which is a part of Kimilsungism-Kimjongilism, is the belief that only through self-reliance and a strong independent state, can true socialism be achieved.

The Workers' Party of Korea (WPK) is the sole ruling party of the Democratic People's Republic of Korea, commonly known as North Korea. Founded in 1949 from a merger between the Workers' Party of North Korea and the Workers' Party of South Korea, the WPK is the oldest active party in Korea. It also controls the Korean People's Army, North Korea's armed forces. The WPK is the largest party represented in the Supreme People's Assembly and coexists with two other legal parties that are completely subservient to the WPK and must accept the WPK's "leading role" as a condition of their existence. The WPK is banned in the Republic of Korea under the National Security Act and is sanctioned by the United Nations, the European Union, Australia, and the United States.
