The Clayton-Cedarmere Estates are located in Roslyn Harbor, New York, United States, listed jointly on the National Register of Historic Places & New York State Register of Historic Places in 1986.

Clayton – the bulk of the property – is the large landscaped Bryce/Frick estate, now home to the Nassau County Museum of Art. Cedarmere – the smaller of the two – is William Cullen Bryant's estate, currently undergoing interior renovation, is located on the west side of Bryant Avenue; overlooking Hempstead Harbor, now a historic house museum. The grounds are open to the public. The two combined properties, with input from several notable architects, illustrate the development of estates on the North Shore of Long Island over a period of nearly a century.^[1]

Bryant originally owned almost the entire property. Fifteen years after Bryant's death, in 1893, Lloyd Bryce bought the largely undeveloped inland portion of the estate and hired Ogden Codman, Jr. to design a mansion for it. In 1919, the dying Henry Clay Frick purchased the estate for his son Childs, who, after renovating it and expanding it, lived there with his family until his 1965 death. Four years later, it was turned over to the county for use as a museum.
