The Poti class was the NATO reporting name for a group of anti-submarine warfare (ASW) corvettes built for the Soviet Navy. The Soviet designation was Project 204 small anti-submarine ships. These ships were the first Soviet warships powered by gas turbine engines; two propellers were mounted in tunnels to give a very shallow draught. A twin 57 mm (2 in) gun mounting provided self-defence.

A total of 66 ships were built between 1960 and 1968. In the Soviet Union the Poti-class corvettes were decommissioned by the late 1980s; some Bulgarian ships served into the 21st century. Builders were:
