Sui Prefecture (Shaanxi)

Suizhou or Sui Prefecture (Chinese: Suīzhōu 綏州; Tangut: 𗉢𗉔) was a zhou (prefecture) in imperial China centering on modern Suide County, Shaanxi, China. It existed (intermittently) from 552 to 1069. In the 10th- and 11th-centuries it was mostly controlled by the Tangut people as part of Western Xia (1038–1227) or its precursor, the Dingnan Jiedushi, although it became Song dynasty territory again in 1067.

The administrative region of Suizhou during the Tang dynasty is in modern northern Shaanxi. It probably includes parts of modern:

• Under the administration of Yulin:
  • Suide County
  • Wubu County
  • Qingjian County
  • Zizhou County
• Under the administration of Yan'an:
  • Zichang County
