Frank Freeman (1861–13 October 1949) 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.
