Van Cortlandt Manor is a 17th-century house and property built by the Van Cortlandt family located near the confluence of the Croton and Hudson Rivers in the village of Croton-on-Hudson in Westchester County, New York, United States. The colonial era stone and brick manor house is now a museum and is a National Historic Landmark.

The Van Cortlandt family was an influential political dynasty from the seventeenth-century Dutch origins of New York through its period as an English colony, then after it became a state, and into the nineteenth century. It rose to great prominence with the award of a Royal Charter to Van Cortlandt Manor, an 86,000-acre (35,000 ha) tract in today's Westchester County sprawling from the Hudson River to the Connecticut state line granted as a Patent to Stephanus Van Cortlandt in 1697 by King William III.
