Lady Sun (孫氏, c.240 – c.334) was a Chinese noble woman of the Eastern Wu during the Three Kingdoms period (220–280 AD) and later the Jin dynasty (266–420 AD). She was a distant relative of Sun Quan and was married to Yu Zhong, the fifth son of Yu Fan, with whom she had a son named Yu Tan.

She lived in the state of Wu until its eventual subjugation by the Jin dynasty, and bore witness to the pivotal conclusion of the era of the Three Kingdoms. During the Jin era, she engaged in some military campaigns, providing financial support to bolster the army. Her contributions played an instrumental role in securing victories for her allies on the battlefield, a feat that would later earn her the title of "Dowager Marchioness of Wuchang" (武昌侯太夫人). Recognizing her exceptional service, court ministers of the time formally acknowledged her accomplishments, and she was recorded in "Biographies of Exemplary Women" in the Book of Jin.
