Hong Chengchou (1593–1665), courtesy name Yanyan and art name Hengjiu, was a Chinese official who served under the Ming and Qing dynasties. He was born in present-day Liangshan Village, Yingdu Town, Fujian Province, China. After obtaining the position of a "jinshi" (進士; successful candidate) in the imperial examination in 1616 during the reign of the Wanli Emperor, he joined the civil service of the Ming Empire and served as an official in Shaanxi. During the reign of the Chongzhen Emperor (r. 1627–1644), he was promoted to Minister of War and Viceroy of Suliao (薊遼; an area which included parts of present-day Shandong, Hebei and Tianjin). In 1642, he surrendered and defected to the Manchu-led Qing Empire after his defeat at the Battle of Songjin. He became one of the Qing Empire's leading Han Chinese scholar-politicians. While he was in office, he encouraged the Manchu rulers to adopt Han Chinese culture and provided advice to the Qing government on how to consolidate its control over the former territories of the fallen Ming Empire. Apart from Dorgon and Fan Wencheng (), Hong Chengchou was regarded as one of the most influential politicians in the early Qing dynasty. However, he was also villainised by the Han Chinese for his defection to the Qing Empire and for his suppression of the Southern Ming dynasty (a short-lived state formed by remnants of the fallen Ming Empire).
