The Hart-Cluett Mansion is located at 57 Second Street in Troy, New York, United States. It was listed on the National Register of Historic Places in 1973, and is a contributing property to the Central Troy Historic District created in 1986. Since the 1950s it, and the Carr Building next door, was the main office of the Rensselaer County Historical Society before the organization changed its name to the Hart Cluett Museum at Historic Rensselaer County in 2019. The house is open to the public as a historic house museum.
