Whitehouse, also spelled White House, is an unincorporated community located within Readington Township in Hunterdon County, New Jersey.

[2] The community lies along the former Jersey Turnpike (now U.S. Route 22), just west of Mechanicsville.

[3] In 1722, Abraham Van Horne purchased 490 acres (2.0 km2) in Readington along the Rockaway Creek.

Around 1750, he built a white plastered wall tavern on the creek where the Jersey Turnpike crossed (this is now the corner of Washington Street and U.S. Route 22).

The settlement included taverns, stores, grist mills, an academy, a Dutch Reformed Church and numerous houses.
