The Fred J. Johnston Museum is a historic house and American antique museum in Kingston, New York. It is one of the contributing properties of the Stockade National Historic District which is listed on the National Register of Historic Places. Built in 1812 by John Sudarn, it was saved from demolition by Fred J. Johnston, who lived in it and also used its rooms as a showplace for his large collection of antique furniture as well as decorative arts items such as glassware, pictoral needlework, and pottery. There are also a few sketches by noted John Vanderlyn, the artist who painted the ceiling in the U.S. Capitol dome. The house is owned and operated by the Friends of Historic Kingston, which was founded in 1965.
The house was built around 1812 by attorney and New York senator John Sudarn, who was friends with author Washington Irving and President Martin van Buren, both of whom Sudarn hosted at his house. The house was sold to the Van Leuven family in the 1880s, whose descendants sold the house in 1938 to Fred Johnston. Johnston spent the rest of his life restoring and maintaining the house. Johnston had an affinity to woodworking and antique furniture beginning at an early age.
