Byeolmuban is the name of a special army unit in the time of Korea's Goryeo Dynasty (918 – 1392). The word "byeol" literally means star, but also has the meaning of special. Founding of the army was initiated by Yoon Gwan during the reign of king Sukjong of Goryeo.

The army was put together to fight the Jurchen who were putting pressure on Goryeo's northern borders. The Goryeo infantry had a hard time resisting the strong Jurchen cavalry.

The "byeolmuban" army had three divisions: infantery called "sinbogun" (神步軍), cavalery called "sinmugun" (神騎軍) and an army of Buddhist monks called "hangmagun" (神步軍).

During the second year of king Yejong of Goryeo's reign the byeomuban, consisting of 170.000 soldiers, attacked Jurchen and took it over.

However internal trouble at the Goryeo court later forced the Goryeo army to leave Jurchen territory.
