The Jean de Vienne is a F70 type anti-submarine frigate of the French Marine Nationale. She is the third French vessel named after the 14th century admiral Jean de Vienne. Her complement is 20% female. On 4 January 2009 Jean de Vienne helped to defend the Croatian tanker Donat, owned by the Tankerska plovidba from Zadar, and a cargo ship from Panama called Vulturnus, off Somalia.

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.
