Note: In this article, to differentiate between the Han state of the Warring States period and the Han dynasty, "Hán" will be used when referring to the former while "Han" will be reserved for the latter.
Xin, King of Hán (died 196 BC), also known as Hán Xin and as Hán Wang Xin, was a noble of the early Han dynasty of China and a descendant of the royal family of Hán during the Warring States period. He was made King of Hán (韓王) in 205 BC by Liu Bang, the founding emperor of the Hàn dynasty, and became a vassal of the Hàn Empire. In 201 BC, after he was suspected of conspiring with the Xiongnu against the Hàn Empire, he defected to the Xiongnu and was eventually killed in a battle between the Hàn Empire and Xiongnu in 196 BC.
