Yang You, also known by his posthumous name as the Emperor Gong of Sui (隋恭帝) (605[5] – 14 September 619?[7][8]), was an emperor of the Chinese Sui dynasty. He was installed as a puppet emperor by Li Yuan. After Li Yuan founded the Tang dynasty, he had Yang You executed.

Following Yang You's death, his brother Yang Tong claimed the Sui throne until 619.

Li Yuan had rebelled against the rule of Yang You's grandfather Emperor Yang of Sui in 617 and captured the Sui capital Chang'an later that year, seizing Yang You and installing him as a puppet emperor. However, only the commanderies under Li Yuan's control recognized Yang You as emperor. The rest of the commanderies continued to recognize Emperor Yang of Sui as emperor. In 618, after news arrived that Emperor Yang had been killed by the general Yuwen Huaji, Li Yuan had the young emperor yield the throne to him. Li Yuan then murdered Yang You a year later.
