Cang Ci 倉慈, courtesy name Xiaoren 孝仁, was an official of the early Wei period 曹魏 (220-265).
He hailed from Huainan 淮南 (modern Shouxian 壽縣, Anhui) and was magistrate (ling 令) of the district of Chang'an 長安 (not the capital city).
Around 230 he was promoted to the post of governor (taishou 太守) of the commandery of Dunhuang 敦煌 in the far west, a commandery he administrated successfully and with Confucian principles. He was responsible for receiving tributary missions from the barbarian tribes in the Western Region (xiyu 西域), and brought about a stable and peaceful situation in this corner of the empire. He was so much venerated by the local population and the foreign tribes that after his death a commemorative shrine was erected.
