Chanel S.A.S. (French [ʃaˈnɛl]) is the name of the fashion group founded by Gabrielle 'Coco' Chanel (1883-1971) with the opening of a Chanel boutique in Deauville in 1913 and today headquartered in Neuilly-sur-Seine near Paris. In the meantime, Chanel has become one of the largest and most important companies in the fashion and cosmetics industry worldwide. In addition to haute couture and prêt-à-porter for women, Chanel also produces high-priced watches, jewelry, eyewear, accessories, perfume and cosmetics in the luxury goods segment for women and to some extent for men.

From the 1910s onwards, the house of Chanel was a pioneer of what was then an unusually functional, casual and yet feminine and elegant women's fashion in the upper price segment. Chanel produced light blouses, airy tops, wide-cut women's trousers or calf-length skirts made of comfortable fabrics in mostly simple designs often borrowed from men's fashion, which freed the women of the time from tight corsets, bodice dresses and stiff skirts with not infrequently opulent embellishments. Coco Chanel's influence on the world of women's fashion was both style-forming and emancipatory. Icons of the Chanel brand include the "little black dress", padded leather handbags with quilted seams and metal link chains, and the Chanel costume with a bordered, collarless tweed jacket and flared skirt. Launched in 1922, Chanel Nº 5 perfume is considered the best-selling in the world.

From the 1970s at the latest, the Chanel brand was associated with wealthy, older ladies. This only changed from the mid-1980s under the direction of Karl Lagerfeld (1933-2019), who designed the house's fashion collections as modern interpretations of Coco Chanel's legacy from 1982 to 2019. He is credited in large part with transforming the then-dusty Parisian fashion house into a billion-dollar international conglomerate by the late 1990s at the latest. Lagerfeld was succeeded by his long-time collaborator Virginie Viard.

Chanel is a privately held company wholly owned by Frenchmen Alain (b. 1949) and Gérard Wertheimer (b. 1950), the grandsons of Pierre Wertheimer (1888-1965), a one-time business partner of Coco Chanel. In fiscal 2017, Chanel's total sales were $9.62 billion.
