The Okehocking Tribe (also known as Ockanickon) was a small band of Unami language-speaking Delaware Indians, who occupied an area along the Ridley and Crum creeks in Delaware County, Pennsylvania. Part of that area is now known as Ridley Creek State Park. Along with the Schuylkill and Brandywine Indians, the Okehocking were known as Unami or "people down the river" by other tribes, in accordance with the Indian way of designating a tribe by geographical location.^[1]

In 1701, the tribe approached William Penn for the purchase of a tract of land. Penn allotted them 500 acres. The tribe used the land as their summer fishing camp, moving north during the winter months.^[2]

At that time, English and European settlers were not allowed to purchase or occupy any land occupied by Indians. Because settlers could not be certain where the boundary lay around Indian land, they tended to build settlements well away from Indian encampments. However, the survey of the 500 acres allotted to the Okehocking Tribe allowed a clear demarcation of where Indian land began and ended. This meant that the settlers could freely camp and build settlements all around the borders without fear of breaking the law. Later, feeling surrounded by colonial settlers, the Okehocking moved west toward the Susquehanna River and later settled in the Ohio River Valley.^[2][3][4]
