The Walking Purchase, also known as the Walking Treaty, was a 1737 agreement between the family of William Penn, the original proprietor of the Province of Pennsylvania, and the Lenape native Indians. In the purchase, the Penn family and proprietors claimed that a 1686 treaty with the Lenape ceded an area of 1,200,000 acres (4,860 km2) in present-day Lehigh Valley and Northeastern Pennsylvania in colonial Pennsylvania, which included a western land boundary extending as far west as a man could walk in a day and a half, which led to its name.
