Gu Yong (168 - 243) was a minister for Eastern Wu during the Three Kingdoms era of China. He learned the classics and calligraphy from Cai Yong when the latter came to Wu briefly as a refugee. His family is one of the four illustrious houses of Wu (Zhu, Lu, Gu, Zhang). He became a governor of several prefectures throughout Yangzhou. He was successful in pacify and integrate rebels and minorities under his jurisdiction.

When Sun Quan became the Prince of Wu, he bestowed the nobility title (Yang Xui Xiang Hou) on Gu Yong. After Sun Quan declared himself the emperor, Gu Yong was appointed to the high rank of Prime Minister.

Gu Yong was said to be a reticent person and a teetotaler, famous for his standards of personal conduct; whenever he spoke, however, he spoke with confidence and reason. He was also known for keeping silent when he disagreed with something; this was a major reason why the emperor often tested his ideas on Gu Yong to see what Gu thought of the concepts - if Gu Yong refused to comment Sun Quan would realise something had not been thought through. Gu Yong was a very modest person who did not repay his enemies with malice but always did everything according to the law.
