Forges et Chantiers de la Gironde (literally translated Forges and dockyards of the Gironde) was a French shipbuilder at Lormont near Bordeaux on the Gironde estuary. The company was previously called Usine de construction navale Chaigneau et Bichon, then Chantiers et Ateliers de la Gironde S.A. Ets Schneider, before becoming Forges et Chantiers de la Gironde. It is today the Construction Navale de Bordeaux (CNB).
The company built naval ships. Its products included the Ottoman Navy Lüft-ü Celil-class ironclads Lüft-ü Celil and Hifz-ur Rahman, the Japanese cruiser Unebi (1886) and Ottoman Samsun class destroyers Basra, Samsun, Taşoz and Yarhisar (all 1907). For the French Navy its ships included the First World War sloop Dédaigneuse (1916),Bougainville-class avisos Bougainville (1931) and Rigault de Genouilly (1932) and the La Galissonnière-class cruiser Gloire (1933).
In June 1939 the yard had launched another Bougainville class aviso, the Beautemps Beaupré. At the Fall of France she was still being completed at the yard so on 24 June 1940 the French took her out into the Gironde and scuttled her to prevent her from being captured. Another Bougainville class aviso, La Pérouse, was on order at the time but was cancelled.
