Bianzhou or Bian Prefecture () was a zhou (prefecture) in imperial China seated in modern Kaifeng, Henan, China. It existed (intermittently) from 576 to Later Jin's reign (936–947).
Eastern Wei first created the Liangzhou and Chengliujung. Northern Qi abolished Kaifengjun which administered Kaifengxian. Northern Zhou Xuandi (578–579) changed the name of Liangzhou to Bianzhou and so Bianshui became its name. The Junyixian was its administrative center, today's Kaifeng. This too was abolished during the Sui Dynasty and the area came under administration of Xingyanjun.
In the year 621, this area was administrated by Zhengzhou, which included Junyixian, Kaifengxian, and Huazhou's Qiuxian.
