Dupleix is a F70 type anti-submarine frigate of the French Marine Nationale. She is the fourth French vessel (beside also two French commercial ships) named after the 18th century Governor of Pondichéry and Gouverneur Général of the French possessions in India marquess Joseph François Dupleix.

Note: The French navy doesn't use the term "destroyer" for its ships; hence some large ships, referred to as "frigates", are registered as destroyers.
