Eastchester is a town in Westchester County, New York, United States. The population was 31,318 at the 2000 census. The town includes the villages of Bronxville and Tuckahoe.
The Town of Eastchester is in the south part of the county.
The town that is now called Eastchester began settlement in 1664 when ten families migrated from Fairfield, Connecticut. Thomas Pell, who at that time also owned the territory that is now New Rochelle and Pelham, granted a deed to the group to "settle down at Hutchinsons'," where the home of Anne Hutchinson had stood some twenty years before. The ten original families were shortly joined by another 26.
