Fairfield was the least densely populated town in Essex County in 2020.

The first Europeans to settle in the area were Dutch and the place was called Gansegat. Later it was part of Horse Neck and officially part of Newark Township. What is now Fairfield was formed on February 16, 1798, as Caldwell Township from portions of Acquackanonk Township and Newark Township. The area was named for Rev. James Caldwell. It was incorporated as one of New Jersey's initial 104 townships by an act of the New Jersey Legislature on February 21, 1798. Portions of the township were taken to create Livingston (February 8, 1813), Fairmount Township (March 11, 1862, now part of West Orange), Caldwell borough (February 10, 1892), Verona Township (February 17, 1892, now known and including what is now Cedar Grove), North Caldwell (March 31, 1898), Essex Fells (March 31, 1902) and West Caldwell (February 24, 1904). On November 6, 1963, Caldwell Township was renamed as Fairfield Township, based on the results of a referendum passed the previous day. Fairfield was reincorporated as borough on June 8, 1964.Snyder, John P. The Story of New Jersey's Civil Boundaries: 1606-1968, Bureau of Geology and Topography; Trenton, New Jersey; 1969. p. 126. Accessed October 25, 2012. In 1978, the borough passed a referendum reincorporating itself as a township, becoming the second of more than a dozen Essex County municipalities to reclassify themselves as townships in order take advantage of federal revenue sharing policies that allocated townships a greater share of government aid to municipalities on a per capita basis."Chapter VI: Municipal Names and Municipal Classification", p. 73.

Accessed September 24, 2015. "In 1978, South Orange Village was the first municipality to change its name to the 'township' of South Orange Village effective beginning in entitlement period 10 (October 1978 to September 1979). The Borough of Fairfield in 1978 changed its designation by a majority vote of the electorate and became the 'Township of Fairfield' effective beginning entitlement period 11 (October 1979 to September 1980).... However, the Revenue Sharing Act was not changed and the actions taken by South Orange and Fairfield prompted the Town of Montclair and West Orange to change their designation by referendum in the November 4, 1980, election. The municipalities of Belleville, Verona, Bloomfield, Nutley, Essex Fells, Caldwell, and West Caldwell have since changed their classification from municipality to a township."Narvaez, Alfonso A. "New Jersey Journal", The New York Times, December 27, 1981. Accessed September 24, 2015. "Under the Federal system, New Jersey's portion of the revenue sharing funds is disbursed among the 21 counties to create three 'money pools.' One is for county governments, one for 'places' and a third for townships. By making the change, a community can use the 'township advantage' to get away from the category containing areas with low per capita incomes."

History The Dutch, including many acculturated French Huguenots, initially settled this area of the Passaic River Valley after purchasing it from the Native Americans. They named it "Gansegat" which is Dutch for "duck's pond".Poekel Jr., Charles A. West Essex: Essex Fells, Fairfield, North Caldwell and Roseland, Arcadia Publishing, 1999, 2004

The Horseneck Tract was an area that consisted of what are now the municipalities of Caldwell, West Caldwell, North Caldwell, Verona, Cedar Grove, Essex Fells, Roseland, and portions of Fairfield, Livingston and West Orange. Later in 1702, English settlers purchased of the Horseneck Tract without approval of the Proprietary Authorities from the Lenape Native Americans for goods equal to $325. When Proprietary Authorities began eviction proceedings against the settlers, the Horseneck Riots took place. This purchase encompassed much of western Essex County, from the First Mountain to a point on the Passaic River at Pine Brook NJ. The reason for the Horseneck name has never been determined, but historians agree that it is not because of its shape.
