The Wappinger were a confederacy of Native Americans whose territory in the 17th century spread along the eastern bank of the Hudson River. Primarily based in what is now Dutchess County, New York, their territory included the east bank of the Hudson along both Putnam and Westchester counties all the way to Manhattan Island to the south, the Mahican territory bounded by the Roeliff-Jansen Kill to the north, and extended east into parts of Connecticut.
