Cao Xie ( third century) was a prince in the state of Cao Wei in the Three Kingdoms period of China. He was a son of Cao Pi, the first emperor of Wei. His mother, whose maiden family name was Li (李), was a concubine of Cao Pi holding the rank of guiren (貴人; translated "Honoured Lady").(文皇帝九男： ... 李貴人生贊哀王恊， ...) Sanguozhi vol. 20. He died early and was posthumously honoured as Duke Shang of Jing (經殤公) in 231 by his half-brother, Cao Rui. In 234, Cao Rui posthumously promoted him to a prince under a new posthumous title: Prince Ai of Zan (贊哀王).(贊哀王協，早薨。太和五年追封謚曰經殤公。青龍二年，更追改號謚。) Sanguozhi vol. 20.
In 235, Cao Xie's only son, Cao Xun (曹尋), inherited the princedom posthumously awarded to his father, and became the Prince of Zan (贊王). In 239, the emperor Cao Fang increased the number of taxable households in Cao Xun's princedom by 500, bringing it up to a total of 3,000. When Cao Xun died in 249, he was posthumously honoured as "Prince Shang" (殤王). As he had no son to succeed him, his princedom was abolished.(三年，子殤王尋嗣。景初三年，增戶五百，并前三千戶。正始九年薨。無子。國除。) Sanguozhi vol. 20.
