Corvette captain is a rank in many navies which theoretically corresponds to command of a corvette (small warship). The equivalent rank in the United Kingdom, Commonwealth and USA is lieutenant commander. The Royal Canadian Navy uses bilingual ranks with capitaine de corvette being the French equivalent of lieutenant commander.

Notable users of the rank of corvette captain in Europe include the navies of France, Germany, Italy and Spain. Other users include many Latin American countries.

While the NATO rank code is OF-3 the official translation of the rank as per NATO STANAG 2116 varies between "commander junior grade" and "commander" (with the next senior rank being translated as "commander senior grade").^[1] Some NATO members class their corvette captains as OF-4 when they are serving afloat.^[1]

The Russian/Soviet equivalent is "captain, 3rd grade" (капита́н 3-го р́анга).
