The 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 XVIIIth Century Governor of Pondichéry and Gouverneur Général of the French possessions in India marquess Joseph Dupleix (see French ship Dupleix for the others).

There are seven ships in the F70 class :

One famous eponymous predecessor in the French Navy was the steam corvette Dupleix which took part in the Japanese Revolution.

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.
