Yuwen Xian (Chinese: 宇文憲) (545–July 18, 578),[1] Xianbei name Pihetu (毗賀突), formally Prince Yang of Qi (齊煬王), was an imperial prince of the Northern Zhou dynasty of China. He was a key official and general during the reign of his brother Emperor Wu, but after Emperor Wu's death he was feared on account of his ability by his nephew Emperor Xuan, who therefore falsely accused him of plotting treason and strangled him.
