Liu Shi (柳奭) (died 25 July – 22 August 659[1]), courtesy name Zishao (子邵), was a chancellor of the Chinese Tang dynasty, during the reign of Emperor Gaozong.
In 659, as part of a campaign of Empress Wu's attempt to take vengeance on anyone who opposed her ascension, Emperor Gaozong issued an edict to have Liu executed.
Empress Wang was sonless, and Liu suggested to her that she should request that Emperor Gaozong's oldest son, Li Zhong, whose mother Consort Liu was of low birth, be created crown prince, so that Li Zhong would be grateful to her.
The situation was exacerbated by the fact that Empress Wang was not good at earning the loyalty of the other concubines and the ladies in waiting, while Consort Wu was able to, and also that Liu Shi and his sister and Empress Wang's mother Lady Liu were not respectful to the other concubines.
Zhangsun was exiled (and soon forced to commit suicide), while Liu and Han were demoted to commoner rank.
Liu Wutian later served in the imperial administration as the commandant of Tan Prefecture (roughly modern Changsha, Hunan).
