Zhongsun Jue 仲孫貜 (died 518 BCE), posthumous title Meng Xizi 孟僖子, was a high minister in the state of Lu 魯 during the Spring and Autumn period 春秋 (770-5th cent. BCE). He was a member of the family Zhongsun 仲孫 (or Mengsun 孟孫), one of the Three Huan families 三桓 that dominated the state of Lu.
Jue was the son of Zhongsun Mie 仲孫蔑 (Meng Xianzi 孟獻子), according to some sources the son of Zhongsun Jie 仲孫羯 (Meng Xiaobo 孟孝伯), and served the dukes Xiang 魯襄公 (r. 573-542) and Zhao 魯昭公 (r. 542-510) of Lu. His older brother Zhongsun Su 仲孫速 (Meng Zhuangzi 孟莊子) was without a proper heir and therefore inherited the title to Jue, but because Jue was still under age in 550 a half-brother of his, Zhongsun Jie, a son of Zhongsun Su's by a concubine, represented the family until his death in 524.
