Jinzhou is an ancient city with over a thousand years of history. Originally known as Tuhe (), it was part of Yan in the Warring States period. Under the Qin dynasty, the majority of what is now Jinzhou became part of Liaodong Commandery. It was part of Changli Commandery in the province of Youzhou during the Han dynasty and Three Kingdoms periods, but fell under the jurisdiction of Yingzhou in the Beiwei, Dongwei, and Beiqi periods, before becoming part of Liucheng Commandery and then Yan Prefecture during the Sui dynasty and Tang dynasty. During the Tang, it was the seat of the Andong Protectorate.
The name "Jinzhou" came into use in the Liao dynasty, when it belonged to Zhongjing prefecture. In the Jin dynasty, it was part of Dongjing Prefecture and Beijing Prefecture. It belonged to Liaoyang Xingzhongshu in the Mongol Empire/Yuan dynasty and to Liaodong township in the Ming dynasty. It was ruled by Tianfu during the Qing dynasty, when its name was changed from Jinzhou to Jinxian. It is also known in English as Chinhsien and Chinchow.
During the Republican period, Jinzhou was attached to Liaoning Province. When the Chinese Civil War resumed in 1945, Jinzhou was the site of a major battle between the Communist and Nationalist forces, since it is where the main route from Manchuria through Shanhai Pass enters central China.
