Buccleuch Mansion is located in Buccleuch Park in New Brunswick in Middlesex County, New Jersey, along the Raritan River.

The house was originally built in 1739 by Anthony White, son-in-law of Lewis Morris, a colonial governor of New Jersey. White built the house for his bride Elizabeth Morris. Their son Anthony Walton White sided with the revolutionaries against the King in the American Revolutionary War. The house was previously known as "The White House Farm." The house was bought by Colonel Joseph Warren Scott in 1821. The house and lands were deeded to the City of New Brunswick to be used as a park in 1911.

Today, the house is looked after by the Jersey Blue chapter of the Daughters of the American Revolution (DAR). Tours are given on Sundays from June through October, and at other times by appointment. The house is decorated with Federal and Victorian furnishings, many of which belonged to the Scott family, owners during much of the 19th century.

Buccleuch is not to be confused with the Buckelew Mansion in Jamesburg, another historic white-painted house in Middlesex County.
