Circassian nationalism is the desire among Circassians worldwide to preserve their genes, heritage and culture, save their language from extinction, raise awareness about the Circassian genocide, return to Circassia and establish a completely autonomous or independent Circassian state in its pre-Russian invasion borders.

The Circassian genocide, or Tsitsekun, was the Russian Empire's systematic mass murder, ethnic cleansing, and expulsion of 95–97% of the Circassian population, resulting in 1 to 1.5 million deaths during the final stages of the Russo-Circassian War. The peoples planned for extermination were mainly the Muslim Circassians, but other Muslim peoples of the Caucasus were also affected. Killing methods used by Russian forces during the genocide included impaling and tearing the bellies of pregnant women as means of intimidation of the Circassian population. Russian generals such as Grigory Zass described the Circassians as "subhuman filth", and glorified the mass murder of Circassian civilians, justified their use in scientific experiments, and allowed their soldiers to rape women.
