Carle Place is a hamlet and census-designated place (CDP) in the Town of North Hempstead in Nassau County, New York, United States. The CDP's population was 4,981 at the 2010 census.
The hamlet draws its name from the Carle House - a 32-room house built by Silas Carle in Westbury in the 1800s. It was called the "Carle Place", and the surrounding area later took the name. An early name (and still-current nickname) for the region is Frog Hollow. As a result, the local high school's sports teams are called the Frogs and the school colors are green and white.Legend has it that as New York City residents and friends of Carle visited Silas Carle, Long Island Railroad conductors would announce "everyone getting off for Carle's Place" to get off the train is how the name Carle Place evolved. In 1946, developer William J. Levitt bought 19 acres (77,000 m2) for an experiment. His crews brought pre-cut lumber to the site and rapidly assembled 600 low-cost houses on a site near the Carle Place station of the Long Island Railroad, offering affordable suburban living with an easy commute into offices in New York City. Within five years, returning veterans and their families swelled the population by 500 percent. It transformed Carle Place, and served as the prototype for the gargantuan development Levitt began the following year a few miles away: Levittown.
