Xiahe County (Chinese: 夏河县; Tibetan: བསང་ཆུ་རྫོང་།) is a county in Gannan Tibetan Autonomous Prefecture, Gansu province, China, bordering Qinghai province to the west.

The town is populated largely by ethnic Tibetans, as well as some Hui and Han Chinese.

The area is highly rural and pastoral (including yak and other animal rearing).

The climate is characterised by mild, rainy summers and frigid, but dry and sunny, winters.
