Cao Ju (birth and death dates unknown) was a son of Cao Cao, a warlord who rose to power in the late Eastern Han dynasty and laid the foundation for the state of Cao Wei in the Three Kingdoms period of China. His mother was Lady Yin (尹夫人), a concubine of Cao Cao. He died early and had no son to succeed him.

In 217, Cao Min (曹敏), a son of Cao Ju's half-brother Cao Jun, was designated as Cao Ju's heir and was enfeoffed as the Marquis of Linjin (临晋侯). In 222, Cao Ju's half-brother Cao Pi, who became the first emperor of the Cao Wei state, honoured Cao Ju with the posthumous title "Duke Min of Fanyang" (范阳闵公). In 224, he promoted Cao Min from a duke to a prince under the title "Prince of Fanyang" (范阳王). In 226, Cao Min's title was changed to "Prince of Juyang" (句阳王). In 232, Cao Pi's successor Cao Rui honoured Cao Ju with a new posthumous title: "Prince Min of Fanyang" (范阳闵王); he also changed Cao Min's title to "Prince of Langya" (琅邪王). Throughout the reigns of the subsequent Wei emperors, the number of taxable households in Cao Min's dukedom increased until it reached 3,400. After Cao Min died, he was posthumously honoured as "Prince Yuan (of Langya)" (原王) and was succeeded by his son Cao Kun (曹焜).
