Danjiangkou (Chinese: 丹江口; pinyin: Dānjiāngkǒu) is a county-level city in northwestern Hubei, China, bordering Henan province to the northeast.

The area of present-day Danjiangkou belonged to both the Han and the Chu during the Warring States period.

[1] In 289 CE, under the Jin Dynasty, the area formed part of the newly established Shunyang Commandery [zh].

[1] During the Yongjia rebellion, many refugees from present-day Linfen, Shanxi settled in Wudang County.
