Liu Rengui (劉仁軌) (602 – March 2, 685), courtesy name Zhengze (正則), formally Duke Wenxian of Lecheng (樂城文獻公), was a general and official of the Chinese dynasty Tang Dynasty, serving as chancellor during the reign of Emperor Gaozong and the subsequent regency of his wife Wu Zetian over his sons Emperor Zhongzong and Emperor Ruizong. He was known for his military prowess, particularly displayed in the conquest of Baekje, as well as political skills that allowed him to maintain good relationships with colleagues and the strong-willed Empress Wu, but was also criticized both by contemporaries and later historians for insincerity.
