Qiao Zhou (c.199[2] - 270), courtesy name Yunnan, was a Chinese astronomer, historian, politician, and writer of the state of Shu Han during the Three Kingdoms period of China.
He previously served under Liu Zhang, the Governor of Yi Province (covering present-day Sichuan and Chongqing) in the late Eastern Han dynasty before becoming a subject of the warlord Liu Bei, who established the Shu Han regime in 221.
He is particularly notable for being the teacher of many Shu Han (and later Cao Wei / Western Jin) officials.
Because of this, Yang Xi earned praise from those individuals who also recognised Qiao Zhou for his talent.
In the 14th-century historical novel Romance of the Three Kingdoms, Qiao Zhou is depicted as an astrologer whose studies greatly aided Zhuge Liang during the Northern Expeditions against Shu's rival state Cao Wei.
