Wei Jiu 魏咎 (d. 208 BCE) was one of the regional rulers at the end of the Qin dynasty 秦 (221-206 BC). He had been a member of the royal house of Wei 魏 during the late Warring States period 戰國 (5th cent.-221 BCE) and bore the title of Lord Ningling 寧陵君.
When Qin conquered the state of Wei, he was demoted to the status of commoner. Immediately after the rebellion of Chen Sheng 陳勝 against the Qin dynasty began, he supported the uprising. General Zhou Shi 周市 liberated the ancient territory of Wei, so that, after some hesitations, Wei Jiu was able to proclaim himself king of Wei.
When the Qin general Zhang Han 章邯 besieged the capital of Wei, Handan 邯鄲, Wei Jiu withdrew to Linji 臨濟 (modern Fengli 封立, Shandong). The relief troops sent by the other regional rulers failed, and for the sake of the population of Linji, Wei Jiu surrendered to Zhang Han and committed suicide.
