Villa Maria is an estate in Water Mill, New York. Built as a private residence in 1887, the villa itself was extensively remodelled by Brooklyn-based architect Frank Freeman in 1919. It later became a convent and spirituality center, before recently becoming a private residence once again. The building is considered a Long Island landmark.

Frank Freeman was a Canadian-American architect based in Brooklyn, New York. A leading exponent of the Richardsonian Romanesque architectural style who later adopted Neoclassicism, Freeman has been called "Brooklyn's greatest architect". Many details of his life and work are however still unknown, and Freeman himself has received little recognition outside academia. Many of his works have been demolished or otherwise destroyed, but most of those that remain have received New York City landmark status, either independently or as part of larger historic districts.
