Zhu Jian 朱建 (d. 177 BCE) was an official during the early years of the Former Han period 前漢 (206 BCE-8 CE).
He failed from the region of Chu 楚 (modern Hubei and Hunan) and served as chief counsellor to Ying Bu 英布, king of Huainan 淮南. It was Zhu Jian recommending to Ying Bu not to rebel against the new emperor of the Han dynasty, Liu Bang 劉邦 (r. 206-195 BCE). He was therefore, after the death of Ying Bu, by Liu Bang granted the title of Lord of Pingyuan 平原君 and was ordered to move to the capital Chang'an 長安 (modern Xi'an 西安, Shaanxi).
He developed a friendship with Shen Yiji 審食其 (sic!), favourite of Empress Dowager Lü 呂太后. Shen Yiji supported the rebellion of the Lü family after the Empress Dowager's death in 180 BCE. For his connection with Shen, Zhu Jian was arrested after the execution of the Lüs and committed suicide a few years later.
