Kichkassia is an extinct genus of prehistoric freshwater ray-finned fish from the order Eurynotoidiformes. It contains only a single species, K. furcae, known from the Middle Permian (Wordian) of European Russia. The former genus Amblypterina and its type species A. costata are considered a junior synonym of it, although some of its species have also been transferred to Isadia.

It had relatively narrow, unspecialized teeth, and may have thus been omnivorous in life, with a primary diet of soft-carapaced invertebrates.
