Clermont State Historic Park / Germantown, New York

The Clermont State Historic Site, also known as the Clermont estate, the Clermont Manor or just Clermont, is a New York State Historic Site in southwestern Columbia County, New York, United States. It protects the former estate of the Livingston family, seven generations of whom lived on the site over more than two centuries.

The estate was established by Robert Livingston following the death of his father, the first Lord of Livingston Manor, in 1728; while most of the manor was inherited by the eldest son Philip Livingston, 13,000 acres (5,300 ha) in the southwest corner, later named Clermont, was willed to Robert. The original house was built about 1740.

Robert Livingston of Clermont died on June 27, 1775 and the estate passed to his son, Robert, who was known as 'Judge Livingston' to distinguish him from his father. Judge Livingston was a member of the New York General Assembly from 1759 to 1768, served as judge of the admiralty court from 1760 to 1763 and was a delegate to the Stamp Act Congress of 1765. He married Margaret Beekman, daughter of Colonel Henry Beekman. Their son, Robert R. Livingston, later known as "Chancellor", served on the committee that drafted the Declaration of Independence. Judge Robert died about six months after his father, on December 9, 1775.

The house is now a New York State Historic Site and was designated a United States National Historic Landmark in 1972. It is a contributing property to another National Historic Landmark, the Hudson River Historic District.

Although located in the town of Clermont, its mailing address is in the nearby town of Germantown.
