Liu Chengyou, Emperor Yin of the Later Han
Liu Chengyou (Chinese: 劉承祐) (28 March 931 – 2 January 951), also known by his posthumous name Emperor Yin (隱皇帝), was the second and last emperor of imperial China's short-lived Later Han dynasty, during the Five Dynasties and Ten Kingdoms period. He reigned from 948 until his death in 951.

Liu Chengyou was only 16 years old when he succeeded his father Liu Zhiyuan, who died abruptly. His reign was marked by the arbitrary killing of his important ministers, which eventually led to his downfall. When he killed the entire family of general Guo Wei without Guo in 951, Guo's army attacked the capital, and Liu Chengyou was killed in the chaos.

There is a reference to Liu Chengyou as "Liu Chenghan" in the epitaph of Liu Jiwen, son of his cousin Liu Yun. Liu Chengyou may thus have changed his name on his accession as emperor.
