A Banderite or Banderovite (; ; ; ) is a name for the members of the OUN-B, a faction of the Organization of Ukrainian Nationalists. The term, used from late 1940 onward, derives from the name of Stepan Bandera (1909–1959), the ultranationalist leader of this faction of the OUN. Because of the brutality utilized by OUN-B members, the colloquial term Banderites quickly earned a negative connotation, particularly among Poles and Jews. By 1942, the expression was well-known and frequently used in western Ukraine to describe the Ukrainian Insurgent Army partisans, OUN-B members or any other Ukrainian perpetrators. The OUN-B had been engaged in various atrocities, including murder of civilians, most of whom were ethnic Poles, Jews, and Romani people.
