The 6th National Congress of the Kuomintang () was held by Wang Jingwei and his followers from the Kuomintang in exile after he defected from Chiang Kai-shek to Japan, in Japanese-occupied Shanghai, on 28 August 1939. As he was a collaborator, this congress was not considered legitimate after the war. A "central political conference" was held in Nanjing later on 20 March 1940, establishing his new regime. The Congress eventually led to the formation of the Reorganized National Government of the Republic of China, a puppet state of Japan under Wang's leadership.
