Wu Jing (died 203) is a general serving under the warlord Sun Jian during the late Han Dynasty period of Chinese history.

He is also Sun's brother-in-law, as his older sister Lady Wu married Sun.

Wu Jing goes to serve under Sun Jian's overlord, Yuan Shu, after Sun is killed in action during the Battle of Xiangyang in 191.

When Yuan Shu declares himself emperor, Wu leaves him and rejoins Sun Jian's forces, which are led by Sun Ce (Sun Jian's oldest son).
