Fu Gu (209–255), courtesy name Lanshi, was an official of the state of Cao Wei during the Three Kingdoms period of China.
Already well known in his 20s, Fu Gu was recommended by Chen Qun to serve the Wei government and was appointed as a low-level official.
After Cao Shuang lost power, he was appointed as Intendant of Henan (河南尹) and Master of Writing (尚書).
In 252, after the death of the Eastern Wu emperor Sun Quan, the Wei generals on the frontline such as Hu Zun, Wang Chang and Guanqiu Jian had the intention of using the opportunity to attack their rival state.
However, Fu Gu, Wang Su and Zhong Hui advised him to personally lead the army instead.
However, Fu Gu and Zhong Hui met up with Sima Zhao, defied Cao Mao's orders, and returned to the capital together.
Fu Gu was later enfeoffed as the Marquis of Yang District (陽鄉侯) and his fief increased by 600 households to a total of 1200.
