The Steuben House is a noted example of Bergen Dutch sandstone architecture, located at New Bridge Landing on the Hackensack River in River Edge, in Bergen County, New Jersey, United States. It was confiscated from Loyalist Jan Zabriskie, and served as a military headquarters through much of the Revolutionary War. General George Washington made it his headquarters, September 4 to 17, 1780. Following the war, it was given to Major General Baron von Steuben, who occupied it from 1783 to 1788. The house was added to the National Register of Historic Places on December 18, 1970, for its significance in architecture and military history. The Steuben Estate Complex, a national historic district, was listed on December 9, 1980, for its significance in architecture, exploration/settlement, and invention. In addition to the Steuben House, the district includes three historic buildings moved from other sites. Named the Ackerman–Zabriskie–Steuben House, it was listed as part of the Early Stone Houses of Bergen County Multiple Property Submission (MPS) on January 10, 1983, for its significance in architecture and exploration/settlement. The Bergen County Historical Society opens the New Jersey State Historic site and two other sandstone houses and barn to the public for special events.

This was called Tantaqua's Plain, where a Hackensack sachem of that name resided with his kinfolk. David Ackerman, residing in the village of Hackensack, purchased the land from Matheus Corneliuson, son of Cornelius Matheus of Hackensack River, in 1695. He devised that portion of this tract of land lying east of Kinderkamack Road to his son, Johannes Ackerman, who built a dwelling on the Steenrapie (Kinderkamack) Road at the time of his marriage to Jannetje Lozier in 1713. A tidal gristmill was built on the Hackensack River. This mill got its power from an artificial pond: the high tide was trapped in the mouth of Cole's Brook by a dam with a special drop-gate, suspended from a horizontal timber. When the tides
