Jiao, Lord of Wey (卫君角), also known asWei Jiao (卫角), was aQin dynasty feudal lord. He was the 44th and the last ruler of the state ofWey. After his death, he did not receive a posthumous name; Jiao was his given name.

Jiao was the heir ofLord Yuan of Wey, but his relationship with Lord Yuan is not clear. According to theRecords of the Grand Historian, he became the lord of Wey nine years beforeQin's unification of China. If the records are correct, his year of accession was 230 BCE,^[1] but according to Japanese historianTakao Hirase, Jiao's year of accession was 241 BCE instead of 230 BCE.^[2] In the first year of his rule, he relocated the state of Wey and its people toYewang.^[3]

After Qin's unification, Wey was the only remaining state out of all the Chinese states established according to the mandate of theZhou dynasty king other than Qin. For reasons unknown,Qin Shi Huang did not remove Jiao from his throne, but EmperorQin Er Shi deposed Jiao and made him a commoner in 209 BCE.^[1] The state of Wey, established in 1040 BCE, was the longest-lasting state from the Zhou dynasty.
