The Valentine–Varian House is a historic house located in the Norwood neighborhood of the Bronx, New York City. Built in 1758 by Isaac Valentine, it is the Bronx's second oldest house and oldest remaining farmhouse. The house remained in the Varian family, which included Isaac Varian, the 63rd Mayor of New York City until 1905, when it was sold. It is currently a part of the Historic House Trust and houses the Museum of Bronx History and the offices of the Bronx County Historical Society. It is a two-story, five bay fieldstone residence with a gable roof. It was moved to its present site in 1965 and restored between July 1965 and May 1968.
