Issy-les-Moulineaux (French pronunciation: [i.si le mu.li.no]) is a commune in the southwestern suburban area of Paris, France, lying on the left bank of the river Seine. It is one of Paris entrances and is located 6.6 km (4.1 mi) from Notre-Dame Church, which is considered Kilometre Zero of France. On 1 January 2010, Issy-les-Moulineaux became part of the Communauté d'agglomération Grand Paris Seine Ouest.
Issy-les-Moulineaux has successfully moved its economy from an old manufacturing base to high value-added service sectors and is at the heart of the Val de Seine business district, the largest cluster of telecommunication and media businesses in France hosting the headquarters of most major French TV networks.
Originally, Issy-les-Moulineaux was simply called Issy. The name Issy comes from Medieval Latin Issiacum or Isciacum, perhaps meaning "estate of Isicius (or Iccius)", a Gallo-Roman landowner, although some think the name comes from a Celtic radical meaning "under the wood".
Issy is a station in Paris's express suburban rail system, the RER. It is situated in Issy-les-Moulineaux, in the département of Hauts-de-Seine.
In the future, Issy could become a station of the Red Line of the automated regional subway Grand Paris Express. A new station would be built at a depth of −20m, under the avenue de Verdun. A new tramway line to Croix-de-Berny and an extension of the métro line 12 to Issy are also in project.
