Guo Si (died 197), also known as Guo Duo (郭多), was a general serving under the warlord Dong Zhuo during the late Han Dynasty period of Chinese history. He assisted Dong in his many campaigns, and was placed under Dong's son-in-law after Dong relocated the imperial capital to Chang'an. He later became one of the de facto regents of Emperor Xian, wherein they occupied the capital and held the emperor and imperial officials hostage. However, his downfall came when he quarreled with another regent, Li Jue, and together with Li, they were defeated by Yang Feng and Dong Cheng, who assisted the emperor to flee the capital. Guo was eventually betrayed and murdered by one of his subordinate generals.

As an early supporter of Dong, he participated most of Dong's major battles, including the subjugation of the Yellow Turbans, the battle of Liang Province, and the war with the coalition against Dong Zhuo.

At the start of the war with the eastern warlords, Guo was sent to assist Niu Fu to develop Mei into an invincible citadel, thus, they built up fortifications and stored 30 years of food supply there before Dong moved the capital to Chang'an from Luoyang. After Hu Zhen and Lü Bu suffered a major defeat from the hands of Sun Jian and Dong's retreat to Chang'an, Niu, Guo and Li Jue were ordered to station in Shan (modern day Shaanxi), which was the front against the anti-Dong-Zhou coalition. At the time the alliance was having internal conflicts and did not focus on fighting Guo and Li, so the senior imperial officer, Zhu Jun could only ask his old friend, Tao Qian to give him a hand in a futile effort to fight the forces of Dong. Tao, despite having a general alliance with Dong, indeed sent 3,000 elite danyang troops to Zhu to battle Guo and Li at Zhongmu, where Zhu was totally crushed. Guo, Li, and Zhang Ji then performed raids around area of Chenliu and Yingchuan, wherein Cao Cao and the likes were unable to stop them, and many residents there were hijacked and enslaved.
