Yang Yong (Chinese: 楊勇; died August 604^[1]), Xianbei name Xiandifa (睍地伐), also known by his posthumous title of Prince of Fangling (房陵王), was a crown prince of Sui dynasty. He was the oldest son of Emperor Wen and Empress Dugu. He drew ire from his parents for wastefulness (which Emperor Wen disliked) and having many concubines (which Empress Dugu disliked), while his younger brother, Yang Guang, whom Emperor Wen and Empress Dugu thought lacked these faults, was favored by them. In 600, Emperor Wen deposed Yang Yong and replaced him with Yang Guang. Subsequently, after Emperor Wen died on 13 August 604^[2] (a death that most historians, while acknowledging a lack of conclusive evidence, believed to be a murder ordered by Yang Guang), Yang Guang had Yang Yong put to death.
