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).

Economic Problems In EHT, there is a flooding population of over 30,000 people and still growing. Several of the trees are being cut down for more pointless buildings. On English Creek Road, there are five banks, dentist office, a h ospital, CVS, Rite Aid, Wawa, Pizza and car wash. That is a lot on a five mile road. Current residents are unhappy that the woods and parks are being cut down for more people to live there. It is too much! In the 1900's there was very little population. Now schoold are overflowing with students. Just recently they changed th Intermidate school into another middle school there was so much students. They put 3rd grade back in Slaughball, and put 5th grade in the Miller school. Now the High School is under a major constution to expand the school area. They might as well add another high school to the overcrowding districk. This is such a crowded town and it is not even on map!
