Righteous armies (Korean: 의병), sometimes translated as irregular armies or militias, were informal civilian militias that appeared several times in Korean history, when the national armies were in need of assistance.

The first righteous armies emerged during the Khitan invasions of Korea and the Mongol invasions of Korea. They subsequently rose up during the Japanese invasions of Korea (1592–1598), the first and second Manchu invasions, and during the Japanese occupation and preceding events.

During the long period of Japanese intervention and annexation from 1890 to 1945, the disbanded imperial guard, and Confucian scholars, as well as farmers, formed over 60 successive righteous armies to fight for Korean freedom on the Korean peninsula. These were preceded by the Donghak movement, and succeeded by various Korean independence movements in the 1920s and beyond, which declared Korean independence from Japanese occupation.
