Farmingdale is an incorporated village on Long Island within the Town of Oyster Bay in Nassau County, New York, United States.

It is also approximately 37 mi (59 km) southeast of Midtown Manhattan and can be reached via the Ronkonkoma Branch of the Long Island Rail Road.

In the 1830s, anticipating construction of the Long Island Rail Road, land developer Ambrose George purchased a large tract of land between a community then known as Bethpage, now Old Bethpage, and an area in Suffolk County known as Hardscrabble.

When the LIRR started service to the area in October 1841,[4][5] it used the name Farmingdale for its latest stop, here, on the line it was building to Greenport.

Stagecoaches took people from the Farmingdale station to Islip, Babylon, Patchogue, Oyster Bay South, and West Neck (Huntington area).

[8] The Lenox Hills Country Club, an 18-hole private golf course designed by Devereux Emmet, was developed north of the community in 1923 and was owned and operated by Benjamin F. Yoakum.

The original 1920s era Lenox Hills subdivision and later adjacent subdivisions, located between the Bethpage State Park golf courses and the Long Island Railroad trackage, encompassing rolling hills and a wide boulevard, are known as the more upscale part of Farmingdale Village.

In 1899, Mile-a-Minute Murphy rode a bicycle along the Long Island Rail Road's Central Branch through the Farmingdale area at a mile a minute.

For many years, the town celebrated its birth with the annual Hardscrabble Fair, with music, food and games.

Many nearby places not within the village limits have Farmingdale as their postal address and the same 11735 ZIP code.

According to the United States Census Bureau, the village has a total area of 1.1 square miles (2.8 km2), all land.
