The Western Qin (CE 385-400, 409-431) is a state of Xianbei ethnicity during the era of Sixteen Kingdoms in China.

Note that the Western Qin is entirely distinct from the ancient Qin Dynasty, the Former Qin, and the Later Qin.All rulers of the Western Qin declare themselves "wang", translatable as either "king" or "prince."

They rule the area that is now the southwestern part of Gansu province in Northwest China.
