Han Xiu (simplified Chinese: 韩休; traditional Chinese: 韓休; pinyin: Hán Xiū) (672–739), courtesy name Liangshi (良士), formally Viscount Wenzhong of Yiyang (宜陽文忠子), was an official of the Chinese dynasty Tang Dynasty, briefly serving as chancellor during the reign of Emperor Xuanzong. His wife was called Liu (died in 784). He was known for his bluntness and honesty.
Han Xiu was born in 672, during the reign of Emperor Gaozong. His family was from the Tang Dynasty capital Chang'an and traced its ancestry to the royal house of the Warring States period state Han. It also claimed, as ancestors, a line of officials during Han Dynasty, Jin Dynasty (265-420), Northern Wei, Northern Qi, Northern Zhou, Sui Dynasty, and Tang. Han Xiu's grandfather Han Fu (韓符) served as a prefectural prefect during Tang, and Han Xiu's father Han Dazhi (韓大智) served as a census official at the eastern capital Luoyang. Han Xiu's uncle Han Damin (韓大敏) was a more-known official who, during the early reign of Emperor Gaozong's wife Wu Zetian, refused to falsely implicate the official Li Xingbao (李行褒), and ultimately, when Wu Zetian executed Li Xingbao anyway, was forced to commit suicide.
