Cao Zhi, courtesy name Zijian, posthumously known as Prince Si of Chen (陈思王), was a prince of the state of Cao Wei in the Three Kingdoms period of China, and an accomplished poet in his time. His style of poetry, greatly revered during the Jin dynasty and Southern and Northern Dynasties, came to be known as the Jian'an style.

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.
