Boulogne-Billancourt (French pronunciation: [bulɔɲ bijɑ̃kuʁ] ; often colloquially called simply Boulogne, until 1924 Boulogne-sur-Seine, [bulɔɲ syʁ sɛn]) is a wealthy and prestigious commune in the western suburbs of Paris, France, located 8.2 km (5 mi) from the centre of Paris. It is a subprefecture of the Hauts-de-Seine department and thus the seat of the larger arrondissement of Boulogne-Billancourt. It is also part of the Métropole du Grand Paris. Boulogne-Billancourt includes one island in the Seine: Île Seguin.

Boulogne-Billancourt is one of the wealthiest regions in the Parisian area and in France.[3] Formerly an important industrial site, it has successfully reconverted into business services and is now home to major communication companies headquartered in the Val de Seine business district.
