The Conestoga wagon, also simply known as the Conestoga, is an obsolete transport vehicle that was used exclusively in North America, primarily the United States, mainly from the early 18th to mid-19th centuries. It is a heavy and large horse-drawn vehicle which, while largely elusive in origin, originated most likely from German immigrants of Pennsylvanian Dutch culture in the Province of Pennsylvania in the early 18th century. The name "Conestoga Wagon" probably derived from the Conestoga River Valley settlement area in the province and saw usage as early as 1717, although it is not known whether the first wagons referred as such had similar builds as later Conestoga wagons.
