Laing House of Plainfield Plantation is a historic house located at 1707 Woodland Avenue in the township of Edison in Middlesex County, New Jersey, United States.

It was built in the early 18th century when the region was being settled by Scottish Quakers in the late 17th and early 18th century,[4] as recalled in the name of The Plainfields and Scotch Plains.

The region was part of the colonial era Elizabethtown Tract and later part of Piscataway Township.

It is not certain whether the name derives from the plain clothing worn by the founders or is a reference to the landscape.

[5] The house was added to the National Register of Historic Places on October 27, 1988, for its significance in exploration and settlement.
