The Big Duck is a ferrocement style building in the shape of a duck. Located in Flanders, New York, the building was originally constructed in Riverhead, New York, and has been moved several times to various locations on eastern Long Island. The building is well-known for its distinctive appearance. This structure inspired the word "duck" to be a common phrase in academic literature used to refer to buildings shaped like everyday objects or describe excessive ornamentation used in graphical presentations of data.
It was originally built in 1931 by duck farmer Martin Maurer and used as a shop to sell ducks, dairy, and duck eggs. It was added to the National Register of Historic Places in 1997. It is a principal building on the Big Duck Ranch, listed on the National Register of Historic Places in 2008.
