The Elijah Miller House is a historic home in North White Plains in Westchester County, New York.

The house is an 18th-century Rhode Island-style farmhouse that was used during the Revolutionary War by General George Washington as a headquarters command post during the Battle of White Plains.

[2] The house, which is now a museum, was home to the average Colonial Westchester Ann and Elijah Miller family and contains many artifacts for public viewing.

[4] By the early 21st century the house was deteriorating from decades of neglect and was open to the public only on a very limited basis.

[5] Due to the hard work of Friends of the Miller House/Washington's Headquarters and Daughters of Liberty's Legacy, Westchester County in May 2017 announced that up to $2 million of funds will be made available to renovate the house.
