Mechanicsville is an unincorporated community located within Readington Township in Hunterdon County, New Jersey, United States. It is located along the New Jersey Turnpike (1806), just east of Whitehouse near the intersection of Lamington Road. The hamlet once had a tavern, a store, numerous mechanic shops as well as a number of residences. As Whitehouse and Mechanicsville lost many of the businesses along the main road, the two hamlets eventually merged. The Whitehouse General Store, the East Whitehouse Fire Department and the Whitehouse United Methodist Church are in the section of Whitehouse that used to be Mechanicsville. The Ryland Inn also was located in this section of Whitehouse.
