The Steregushchiy class, Russian designation Project 20380, is a class of corvettes being built for the Russian Navy. Designed by the Almaz Central Marine Design Bureau, subsequent vessels were built to an improved design, incorporating the Zaslon-Redut SAM system. The ship full displacement and dimensions are large for a corvette, thus it is designated as a frigate by NATO. The Steregushchiy class has been further developed into the Gremyashchiy class and Project 20386 subclasses. The export variant is known as Project 20382 Tigr.

The Russian navy is the naval arm of the Russian Armed Forces. It has existed in various forms since 1696; its present iteration was formed in January 1992 when it succeeded the Navy of the Commonwealth of Independent States.
