Lu Gong(?-192) was an officer under Liu Biao. He served as the envoy who requested aid from Yuan Shao when Liu Biao was surrounded by Sun Jian's army. Following Kuai Liang's plan, he succeeded in luring Sun Jian into an ambush. When Sun Jian died, a vengeful Cheng Pu charged him and Lu Gong fell to a spear thrust.
