Cao Huan (246-303), formally known as Emperor Yuan of Wei, was the fifth and last emperor of the state of Cao Wei during the Three Kingdoms period of Chinese history.
In 265, Cao abdicated in favor of Sima Yan, then Emperor Wu of the Jin Dynasty, and was granted the title of "Prince of Chenliu" (陳留王), which he carried until his death. After his death, he was buried with honors befitting that of an emperor and given a posthumous name.
