The September 1946 Korean general strike was a nationwide strike led by the Communist Party of Korea in which more than 250,000 workers participated. It was fuelled by a growing independence movement after the imposition of the United States Army Military Government in Korea (USAMGIK). Although the strike's events were studied by the South Korean Truth and Reconciliation Commission from 2005 to 2010, they remain disputed.

The Communist Party of Korea was a communist party in Korea. It was founded during a secret meeting in Seoul in 1925. The Governor-General of Korea had banned communist and socialist parties under the Peace Preservation Law, so the party had to operate in a clandestine manner. The leaders of the party were Kim Yong-bom and Pak Hon-yong.
