The Steregushchiy class (Russian: стерегущий – "vigilant") is the newest class of corvette in the Russian Navy. It was designed by the Almaz Central Marine Design bureau. The first ship was designated Project 2038.0 (or 20380) by the Russian Government; subsequent vessels were built to an improved design, Project 20381. At 2,200 tons it is large for a corvette and is designated as a frigate by NATO. Project 20382 "Tigr" is an export variant that has been ordered by Algeria. Project 20385 is another variant.

This type has been further developed into the Gremyashchiy-class corvette and Derzky-class corvette.

The ships of the Steregushchiy class are multipurpose corvettes, designed to replace the Grisha class. Such ships are used for littoral zone operations, engagement of enemy submarines and surface ships, and gun support of landing operations. The first batch being built at the Severnaya Verf shipyard in St. Petersburg consists of four ships. A second building line has been started at Komsomolsk. The lead ship of this second batch will be named Sovershennyy.

The Russian Navy has publicly announced that they expect to buy at least 30 of these ships, for all four major fleets.

According to Jane's Naval Forces News, the first vessel was commissioned on 14 November 2007.

In 2007 the Indonesian Navy made an agreement in principle (pending a full contract) for four vessels of this type to replace their ageing Dutch-built Fatahillah-class corvettes. The first was to be built in Spain and fitted out in St. Petersburg, leaving open the option of Indonesian involvement in building the subsequent ships. This agreement appears to have lapsed; in 2011 Indonesia signed a deal for two Milgem-class corvettes from Turkey. Rosoboronexport have briefed Singapore and the United Arab Emirates on the vessel.
