Gironde (/ʒɪˈrɒnd/ zhih-ROND,[3] US usually /dʒɪˈ-/ jih-,[4][5] French: [ʒiʁɔ̃d] ⓘ; Occitan: Gironda, pronounced [dʒiˈɾundo]) is the largest department in the Nouvelle-Aquitaine region of Southwestern France.

From 1793 to 1795, the department's name was changed to Bec-d'Ambès to avoid the association with the Girondist political party of the French Revolution.

[7] Gironde is part of the current region of Nouvelle-Aquitaine and is surrounded by the departments of Landes, Lot-et-Garonne, Dordogne and Charente-Maritime and the Atlantic Ocean on the west.

If overseas departments are included, however, Gironde's land area is dwarfed by the 83,846 km2 of French Guiana.

Gironde is well known for the Côte d'Argent beach which is Europe's longest, attracting many surfers to Lacanau each year.
