fcuk（French Connection United Kingdom）是英国服装公司French Connection所拥有的服饰品牌。成立于1972年，初期只以「French Connection」作为品牌名的该公司，自1997年时开始大规模地推广其新的品牌名称缩写「fcuk」（通常采全小写方式标示），由于名称缩写十分接近英文粗口「fuck」而容易被混淆，反而帮助了知名度的提高。主要销售地区为欧洲、北美、亚洲与澳大利亚的French Connection，总部设于伦敦。

The French Connection was a scheme through which heroin was smuggled from Turkey to France and then to the United States through Canada. The operation reached its peak in the late 1960s and early 1970s, and was responsible for providing the vast majority of the heroin used in the United States. The operation was headed by Corsican criminals Paul Carbone (and his associate François Spirito) and Antoine Guérini, and also involved Auguste Ricord, Paul Mondoloni and Salvatore Greco. Most of the operation's starting capital came from assets that Ricord had stolen during World War II when he worked for Henri Lafont, one of the heads of the Carlingue (French Gestapo) during the German occupation in World War II.
