History

While known as Old Fields, in 1842, the Henry Smith Farmstead was the site of the murder of farmer Alexander Smith and his wife. The suspect was a German employed by Mr. Smith with a reported motive of theft. The town was renamed Greenlawn following the expansion of the Long Island Rail Road in 1871, which connected to the nearby villages of Northport and Port Jefferson. The LIRR chose the name Greenlawn for its station, apparently to project an idyllic rural/suburban image and foster resort travel to the beaches in Centerport.

Greenlawn was well known for its pickle production during the 19th century, as well as, to a lesser degree, potato and cabbage farms. An escaped enslaved man, Samuel Ballton earned the moniker "The Pickle King" following his success in gathering pickles. The principal commodity, pickles, is still celebrated by the annual Pickle Festival, hosted by the local Greenlawn-Centerport Historical Association.
