Guan Suo is a fictional character of the Three Kingdoms period of China.
Many tales about him were passed down in the form of folk culture instead of textual works.
In the 14th-century historical novel Romance of the Three Kingdoms, Guan Suo was described as a capable warrior, and was involved in Zhuge Liang's Southern Campaign against the Nanman.
Sources such as Genealogy of the Guan Family (關氏家譜), Guang Yi Si Dian (廣義祀典) and Kaozheng on the Holy Emperor's Genealogy (聖帝世系考證) claim that Guan Suo's courtesy name was Weizhi (維之).
Guan Suo is featured as a playable character in the seventh instalment of Koei's Dynasty Warriors video game series.
