Cao Zhang, courtesy name Ziwen, nickname "The Yellow Goatee" (黃鬚兒), was a prince of the state of Cao Wei during the Three Kingdoms period of China. He was a son of Cao Cao, a warlord who rose to power towards the end of the Han dynasty and laid the foundation of Wei. Cao Zhang was said to have wrestled and killed wild animals with his bare hands. He also served as a general under his father, having led his troops to significant victories against Wuhuan incursions on the northern frontier.

Wei (220–266), known as Cao Wei (曹魏) or Former Wei in historiography, was a dynastic state of China and one of the three major states that competed for supremacy over China in the Three Kingdoms period. With its capital initially located at Xuchang, and thereafter Luoyang, the state was established by Cao Pi in 220, based upon the foundations laid by his father, Cao Cao, towards the end of the Eastern Han dynasty.
