Grigory Khristoforovich von Zass (Russian: Григорий Христофорович фон Засс; German: Georg Otto Ewald Freiherr von Saß; 1797–1883) was an Imperial Russian general who commanded Russian cavalry troops in the Napoleonic Wars and Russo-Circassian War, initially gaining prominence for his actions against the Circassians, whom he reportedly saw as a "lowly race". He was the founder of the city of Armavir, Russia.

In 2003, the Russian Federation erected his statue on former Circassian territories, infuriating Circassians and Circassian nationalist establishments worldwide.
