Gongsun Gong was a minor warlord during the late Han Dynasty and Three Kingdoms period of Chinese history. He was the younger brother of Gongsun Kang and son of Gongsun Du. Gongsun Gong advised his brother to kill Yuan Xi and Yuan Shang and deliver their heads to Cao Cao. After the death of Gongsun Kang, Gongsun Gong inherited the lordship of Xiangping. Cao Pi confirmed the lordship and gave Gongsun Gong the rank of General of the Flying Cavalry. In 228, Gongsun Yuan, the son of Gongsun Kang, took away his uncle's power and imprisoned him. He was released after Sima Yi totally defeated Gongsun Yuan in 238.
