Xiao Zhizhong (蕭至忠; died July 29, 713?) was an official of the Chinese dynasty Tang Dynasty and Wu Zetian's Zhou Dynasty, serving as a chancellor during the reigns of Wu Zetian's sons Emperor Zhongzong and Emperor Ruizong and grandsons Emperor Shang and Emperor Xuanzong. He was known for his willingness to point out corruption in high level officials, but was later himself implicated as a partisan of the powerful Princess Taiping (Emperors Zhongzong's and Ruizong's sister) and executed in 713 when Emperor Xuanzong suppressed Princess Taiping's party.
