Harvey Cedars is a borough in Ocean County, New Jersey, United States. As of the 2010 United States Census, the borough's population was 337, reflecting a decline of 22 (-6.1%) from the 359 counted in the 2000 Census, which had in turn declined by 3 (-0.8%) from the 362 counted in the 1990 Census. The borough borders the Atlantic Ocean on Long Beach Island.
Harvey Cedars was incorporated as a borough by an act of the New Jersey Legislature on December 15, 1894, from portions of Union Township (now Barnegat Township), based on the results of a referendum held on November 20, 1894.
The majority of the housing units in the borough are seasonal houses used primarily in the summer by owners who live elsewhere, bringing the summer population to 12,000. The borough's quiet character and bay and ocean access make housing very expensive, with many bay or oceanfront houses priced at $2 million or more. Despite the borough's small size, its property was assessed at over $1.28 billion in 2019.
Before Long Beach Island was developed, its northern area, from the Barnegat Inlet to the Great Swamp (now Surf City), was covered with Atlantic white cedar (chamaecyparis thyoides). Early inhabitants of the area harvested salt hay (spartina patens) and seaweed to make a living.
The earliest reference to the area was a deed from 1751 that called the place "Harvest Quarters". The name "Harvey Cedars" may be derived from the "harvest" housing used by these farmers and the "cedars" that grew in the area.
According to the United States Census Bureau, the borough had a total area of 1.19 square miles (3.08 km2), including 0.56 square miles (1.45 km2) of land and 0.63 square miles (1.62 km2) of water (52.61%).
