The Grisha class, Soviet designation Project 1124 Al'batros, are a series of anti-submarine corvettes built by the Soviet Union between 1970 and 1990 and later by Russia and Ukraine. These ships have a limited range and are largely used only in coastal waters. They have been equipped with a variety of ASW weapons and an SA-N-4 'Gecko' surface-to-air missile launcher. All were fitted with retractable fin stabilizers.

The designation "corvette" for these ships was a conditional adaptation as the Soviet classification was a small anti-submarine ship (Russian: Малый противолодочный корабль, romanized: Malyy protivolodochnyy korabl, lit. 'Small anti-submarine ship') (MPK). In the Russian Navy, the Grishas are expected to be partially replaced by the Steregushchiy-class corvette.
