Hageman Farm is a historic house at 209 South Middlebush Road in Somerset, New Jersey, recognized as a registered historic place of New Jersey and now operating as a museum. It reflects the long presence of the Hageman family in North America, beginning with Catherine and Adrian Hegeman, who emigrated from the Netherlands around 1650 or 1651 and first settled in Flatbush, New York. In 1702, four of their grandsons moved to the Six Mile Run area of New Jersey, connecting the family name to the local landscape represented by Hageman Farm.
