Edgewater was first settled by the Lenape Indians who traded up and down the Hudson River. They referred to it as KIN-NAS-NA-KI-KING which in English means LONG PASTURE. In 1894 it was incorporated as the Borough of Edgewater by which it is now known. Originally Edgewater was a summer resort for wealthy New York families who came by boat and stayed at the luxurious Octagon House built high on the Palisades.
