Greenlawn, NY

Two September traditions keep Greenlawn's farming and volunteer-service history in public view. The Greenlawn Fire Department opens Labor Day weekend with a parade down Broadway, followed by four nights of food, games, and raffles at its headquarters; the department identifies the event as New York's longest-running fireman's fair. Later in the month, the Greenlawn-Centerport Historical Association holds its Pickle Festival at John Gardiner Farm, with the forty-sixth edition scheduled for 2026. The festival recalls an era when local farms raised pickling cucumbers, potatoes, and cabbage. Samuel Ballton, who escaped slavery during the Civil War and settled here in 1873, became such a productive cucumber grower that he was remembered as Greenlawn's Pickle King. The community itself was called Old Fields before the railroad's arrival brought the Greenlawn name in 1871.

Harborfields Public Library gives the hamlet a heavily used indoor counterpart to those outdoor events. It opens four evenings a week, runs programs for children, teens, and adults, and lets cardholders reserve Studio31 for podcasting and audio recording. Nearby Greenlawn Park has lighted ball fields, a playground, picnic area, and a 9,200-square-foot skate park designed for skateboards, scooters, BMX bikes, and inline skates. Greenlawn held 13,661 residents in 2020. Census estimates for 2020 through 2024 put owner occupancy at 83 percent, the median owner-occupied value at $630,800, and monthly costs for mortgage holders at $3,752. Median household income was $164,427, workers averaged about 36 minutes of travel to work, and 27 percent of people age five or older spoke a language other than English at home.
