Egg Harbor Township is a township in Atlantic County, New Jersey, United States. As of the 2000 census, the township population was 30,726. The Census Bureau's 2004 population estimate for the township was 39,863, representing growth of nearly 20% since the previous enumeration. Egg Harbor Township was first mentioned as part of Gloucester County in records dating back to March 20, 1693, and at times was called New Weymouth. The township's western boundary was established on May 13, 1761, with the area called Great Egg-Harbour township. Portions of the township were taken to form Galloway Township, which was established by Royal Charter on April 4, 1774. Additional portions were taken to form Weymouth Township on February 12, 1798. On February 21, 1798, the area was incorporated as Egg-Harbour Township. Over the ensuing centuries, portions of the township were taken to create many new municipalities: Hamilton Township on February 5, 1813; Atlantic City on May 1, 1854; Absecon on May 1, 1854; South Atlantic City (now Margate City) on September 7, 1885; Pleasantville on January 10, 1889; Linwood on February 20, 1889; Somers Point on April 24, 1886; Longport on March 7, 1898; Ventnor City on March 17, 1903; and Northfield on March 21, 1905. Great Egg Harbor got its name from Dutch explorer Cornelius Jacobsen Mey. In 1614, Mey came upon the inlet to the Great Egg Harbor River. The meadows were so covered with shorebird and waterfowl eggs that he called it "Eyren Haven" (Egg Harbor).
