Yao Chong (; 650 – September 28, 721), né Yao Yuanchong (姚元崇), known 700s–713 by the courtesy name of Yuanzhi (元之), formally Duke Wenxian of Liang (梁文獻公), was an official of the Chinese Tang dynasty and Wu Zetian's Wu Zhou dynasty, serving as chancellor under four sovereigns—Wu Zetian, her sons Emperor Zhongzong and Emperor Ruizong, and her grandson Emperor Xuanzong. After his resignation in 716, he still had great influence inside the imperial government, and his opinions often influenced the decisions of Emperor Xuanzong and the succeeding chancellors.
