Russian National Unity or All-Russian civic patriotic movement "Russian National Unity" was an unregistered neo-Nazi, irredentist group based in Russia and formerly operating in states with Russian-speaking populations. It was founded in 1990 by the ultra-nationalist Alexander Barkashov. The movement advocated the expulsion of non-Russians and an increased role for traditional Russian institutions such as the Russian Orthodox Church. The organization was unregistered federally in Russia, but nonetheless collaborated on a limited basis with the Federal Security Service. The group was banned in Moscow in 1999 after which the group gradually split up in smaller groups and their webpage became defunct in 2006.

Neo-Nazism comprises the post–World War II militant, social, and political movements that seek to revive and reinstate Nazi ideology. Neo-Nazis employ their ideology to promote hatred and racial supremacy, to attack racial and ethnic minorities, and in some cases to create a fascist state.
