Sun Ce (175 – 200) was a military general and warlord during the late Eastern Han Dynasty and Three Kingdoms era in ancient China. He was the eldest of five sons and one daughter of Sun Jian, who was killed in battle when Sun Ce was only sixteen. Sun Ce then broke away from his father's former overlord Yuan Shu and headed into Southeastern China to establish his own power base there. With the help of several capable men, including Zhang Zhao and Zhou Yu, Sun Ce managed to lay down the foundation of the later Eastern Wu, of which his younger brother Sun Quan eventually became the first emperor. After Sun Quan declared himself emperor, he posthumously honored Sun Ce with the title Prince Huan of Changsha (长沙桓王, literally "the diligent prince").

In 200, when the rising warlord Cao Cao was away battling Yuan Shao in the decisive Battle of Guandu, Sun Ce was rumored to be plotting an attack against Cao Cao's capital of Xuchang. However, he was assassinated before he could carry out the plan.

The Chronicles of the Three Kingdoms describes Sun Ce as handsome and full of laughter. He was also a generous and receptive man who could employ people according to their abilities. Thus his subjects were willing to risk their lives for him. One detractor named Xu Gong, in a letter to Emperor Xian, likened Sun Ce to Xiang Yu, the general renowned for overthrowing Qin Dynasty . As Xiang Yu was often referred to as the Conqueror of Chu, Sun Ce henceforth became known as the Little Conqueror in popular culture.
