The Township of Neptune extends over an area of 8.8 square miles, of which, 8.2 square miles of it is land and 0.5 square miles of it (6.16%) is water. Neptune Township is located in Monmouth County and stretches from the Atlantic Ocean west to the Garden State Parkway (exit 100). The southern border is the Shark River estuary and the northern border is with the City of Asbury Park and Ocean Township.
The physical appearance of Neptune today is the result of land use and urban design decisions made mostly during the first half of the past century. Neptune Township was incorporated as a township by an Act of the New Jersey Legislature on February 26, 1879, from portions of Ocean Township. Portions of the township were taken to form Neptune City (October 4, 1881), Bradley Beach (March 13, 1893) and Ocean Grove (April 5, 1920, until it was found unconstitutional and restored to Neptune Township as of June 16, 1921). Ocean Grove and Shark River Hills are census-designated places and unincorporated areas located within Neptune Township. Other communities within Neptune Township are Mid-Town, Bradley Park, the Gables, Summerfield, Green Grove, Seaview Island and West Neptune.
Roads were constructed in the early part of the 20th century. As transportation and infrastructure improvements were constructed, the number of residents in Neptune began to rise. The construction of the Garden State Parkway between 1946 and 1957 resulted in significant population gains in the Township, as the population nearly doubled between 1950 and 1960.
