Kingscote is a Gothic Revival mansion and house museum at Bowery Street and Bellevue Avenue in Newport, Rhode Island, designed by Richard Upjohn and built in 1839. It was one of the first summer "cottages" constructed in Newport, and is now a National Historic Landmark. It was remodeled and extended by George Champlin Mason and later by Stanford White. It was owned by the King family from 1864 until 1972, when it was given to the Preservation Society of Newport County.
