Jiao Province (交州) was the southernmost province of the Han empire, covering what is now Guangdong, Guangxi and northern Vietnam. It is the same region described in the sources as Jiaozhou; see also Jiaozhou.
Under Eastern Wu the province lay at the edge of Wu’s reach and was often used as a place of exile. After the dispute over merit at Quebei, Gu Tan, Gu Cheng, and Zhang Xiu were banished to Jiao Province, where they died far from the Wu court.
