Greenlawn, New York, United States

🇺🇸 Greenlawn is a hamlet and place (CDP) in Suffolk County, New York, United States. It is located on Long Island in the Town of Huntington. Students primarily attend the Harborfields Central School District.

History Originally known as Old Fields, it became known by the name Greenlawn with the coming of the Long Island Rail Road in 1870 or 1871. 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; the principal commodity, pickles, is still celebrated by the annual Pickle Festival, held by the local Greenlawn-Centerport Historical Association at the John Gardiner Farm. The Gardiner family was the first to make a name for themselves as pickle farmers in the region but a former enslaved man, Samuel Ballton, earned the moniker "The Pickle King" for becoming a prolific pickle farmer in Greenlawn in the early 1900s.
