Xiazhou or Xia Prefecture (夏州) was a "zhou" (prefecture) in imperial China centering on modern Jingbian County, Shaanxi, China. It existed (intermittently) from 487 to early 13th century, when the Mongolian Yuan dynasty destroyed Western Xia (1038–1227). In the 10th-, 11th and 12th-centuries it was mostly controlled by the Tangut people as part of Western Xia or its precursor, the Dingnan Jiedushi.
