Wappingers Falls is a village in the towns of Poughkeepsie and Wappinger, in Dutchess County, New York, United States. As of the 2020 census, Wappingers Falls had a population of 6,103. The community was named for the cascade in Wappinger Creek. The Wappingers Falls post office covers areas in the towns of Wappinger, Poughkeepsie, Fishkill, East Fishkill, and LaGrange. This can result in some confusion when residents of the outlying towns, who do not live in the village, give their address as "Wappingers Falls".
