Philipsburg Manor (sometimes referred to as Philipse Manor) was a manor located north of New York City in Westchester County in the Province of New York. Netherlands-born Frederick Philipse I and two partners made the initial purchase of land that had been part of a Dutch patroonship owned by Adriaen van der Donck. Philipse subsequently bought his partners out and added more land before being granted a royal charter in 1693 for the 52,000 acres (21,000 ha) estate, becoming its first lord.
