Xin, King of Hán (died 196 BC), also known as Hán Xin and as Hán Wang Xin, was a descendant of the royal family of the state of Hán during the Warring States period of China. After the establishment of the Han dynasty, Emperor Gaozu granted Hán Xin the title of "King of Hán" (韓王). In 201 BC, Hán Xin was suspected of conspiring with the Xiongnu to attack the Han Empire and decided to defect to the Xiongnu. He was killed in action during a battle against the Han army in 196 BC.
