Frigate captain is a naval rank in the naval forces of several countries.

It is, usually, equivalent to the Commonwealth/US Navy rank of commander.

Countries using this rank include Argentina and Spain (Spanish: capitán de fragata), France (French: capitaine de frégate), Belgium (Dutch: fregatkapitein), Italy (Italian: capitano di fregatacode: it is deprecated ), Brazil and Portugal (Portuguese: capitão de fragata) Croatia (Croatian: kapetan fregate ) and Germany (German: Fregattenkapitän) .

In the Royal Canadian Navy, capitaine de frégate is the official French language name for the rank of commander.

The NATO rank code is OF-4, the official translation for instance of the German Fregattenkapitän as well as the French capitaine de frégate into English is "commander senior grade".^[1]

The Russian/Soviet equivalent is "captain of the 2nd rank" (капитан 2-го ранга)
