The Esopus tribe was a tribe of Lenape (Delaware) Native Americans who were native to Upstate New York, specifically the region of the Catskill Mountains. Their lands included modern-day Ulster County and Sullivan County, New York. The tribe fought a series of conflicts against settlers from the New Netherland colony from September 1659 to September 1663, known as the Esopus Wars in and around Kingston, New York. At the conclusion of the conflict, the tribe sold large tracts of land to French Huguenot refugees in New Paltz and other communities.
