Jiangkou is a county in China under the jurisdiction of Tongren, a prefecture-level city in the northeast of Guizhou Province. Its county government is seated in Shuangjiang.
It should not be confused with other places in China that share the name Jiangkou, including locations in Gansu. The Jiangkou described here is the county-level administrative unit in Guizhou, and its administrative identity is tied to Tongren rather than to any similarly named settlement elsewhere.
Beyond its administrative status and the location of its seat of government in Shuangjiang, few details are firmly established in the available reference material. The county forms part of Tongren's jurisdiction within northeastern Guizhou.
