Crestwood is a neighborhood in Yonkers, New York. Located in northeastern Yonkers, Crestwood is separated by the Bronx River from the village of Tuckahoe. Because the majority of Crestwood is served by the Tuckahoe post office, many residents identify their location as Tuckahoe or Crestwood, rather than Yonkers. Closer to the Crestwood train station, several grand homes occupy the hilly ground overlooking the river.
