Shizuishan, formerly Shizuizi, is a prefecture-level city in the Ningxia Hui Autonomous Region of the People's Republic of China.

It is the northernmost prefecture in Ningxia and the second most populous, after the regional capital Yinchuan, bordered by Inner Mongolia to all directions except the south.

[8] In 1934, Shizuishan was occupied by the army of warlord Sun Dianying during his attempt to conquer Ningxia from the Ma clique.

Sun set up a rival provincial government in the town,[9] but he was eventually defeated by Ningxia's official governor Ma Hongkui.

Shizuishan experiences a cool arid climate (Köppen BWk) with freezing and very dry winters, alongside very warm to hot and somewhat wetter summers.
