Honghuzi () were armed Chinese robbers and bandits who operated in the areas of the eastern Russia-China borderland during the second half of the 19th century and the first half of the 20th century. Their activities extended over southeastern Siberia, the Russian Far East, and Manchuria/Northeast China. The word honghuzi has been variously transliterated as hong huzi, hunhutsi, hong hu zi, hunghutze, hun-hutze, etc. There is also a common transliteration from Russian, khunkhuzy (), and a back-formation for the singular, khunkhuz (). Korean immigrants to Manchuria in the 20th century called the honghuzi ma-jeok (마적,馬賊). Groups of honghuzi were recruited as guerrillas by the Imperial Japanese Army during the Russo-Japanese War of 1904-1905 into sabotage units.
