Harley-Davidson, Inc., or Harley, is an American motorcycle manufacturer, founded in Milwaukee, Wisconsin in 1903.

As one of two major American motorcycle manufacturers to survive the Great Depression (along with Indian), the company has survived numerous ownership arrangements, subsidiary arrangements (e.g., Aermacchi 1974-1978 and Buell 1987-2009), periods of poor economic health and product quality, as well as intense global competition — to become the world’s largest motorcycle manufacturer and an iconic brand widely known for its loyal following — with owner clubs and events worldwide as well as a company sponsored brand-focused museum.

Noted for a style of customization that gave rise to the chopper motorcycle style, Harley-Davidson traditionally marketed heavyweight, air-cooled cruiser motorcycles with engine displacements greater than 700 cm³ — and has broadened its offerings to include its more contemporary VRSC (2002) and middle-weight Street (2015) platforms.

Harley-Davidson manufactures its motorcycles at factories in York, Pennsylvania; Milwaukee, Wisconsin; Kansas City, Missouri; Manaus, Brazil; and Bawal, India — and markets its products worldwide.
