Arrowheads and pottery shards have been found by residents by the banks of the Cooper River, hinting that there was a Native American settlement in Haddonfield at one point in time.

On October 23, 1682, Francis Collins, an English Quaker and a bricklayer by trade, became the first settler within the boundaries of what today is Haddonfield.

Shortly after her arrival, she made a marriage proposal to John Estaugh, a Quaker minister, and they were married in 1702.

[26] The Indian King Tavern, built in 1750, played a significant role in the American Revolutionary War.

In 1838, William Estaugh Hopkins uncovered large bones in a marl pit in which he was digging.

In 1858, Foulke dug from the marl pit the first relatively complete skeleton of a dinosaur found in North America, Hadrosaurus foulkii.

[30] A 17-foot (5.2 m) long bronze sculpture of “Haddy”, by sculptor John Giannotti, stands in the center of town.

[33] Haddonfield is home to the second oldest volunteer fire company in continuous service in the United States.

Each member was to furnish two leather buckets while the company supplied six ladders and three fire hooks.

[35] In keeping with the historic appearance of the borough, some candidates for commissioner distribute colored ribbons to their supporters instead of yard signs.

It has since been declared a State Historic Site, restored to its original layout, and turned into a museum with guided tours available to the public.

[3][64][65][66] In July 2019, Robert Marshall was selected to fill the seat as commissioner that became vacant following the resignation of John Moscatelli the previous month.

[70] Borough Hall, the home of Haddonfield government, is located at 242 King's Highway East and was built in 1928 by Walter William Sharpley.

[71] In Borough Hall's auditorium are paintings of men who signed the United States Declaration of Independence from New Jersey: Abraham Clark, Francis Hopkinson, Richard Stockton, and John Witherspoon.

[75][76][77] For the 119th United States Congress, New Jersey's 1st congressional district is represented by Donald Norcross (D, Camden).

[101][102] In the 2008 presidential election, Democrat Barack Obama received 59.4% of the vote (4,346 cast), ahead of Republican John McCain, who received around 38.2% (2,793 votes), with 7,311 ballots cast among the borough's 8,970 registered voters, for a turnout of 81.5%.

[103] In the 2004 presidential election, Democrat John Kerry received 54.1% of the vote (3,946 ballots cast), outpolling Republican George W. Bush, who received around 44.7% (3,264 votes), with 7,300 ballots cast among the borough's 8,912 registered voters, for a turnout percentage of 81.9.

[134] Christ the King Regional School, founded in 1940, serves students in Pre-K3 through eighth grade and operates under the auspices of the Roman Catholic Diocese of Camden.

The fall festival is an event where community organizations may have booths along Kings Highway and there is scarecrow-making for kids.

There is also the Haddonfield Crafts & Fine Arts Festival, where a large variety of vendors line the main street.

Another event is First Night, a New Year's Eve celebration of the arts, with a variety of performances was held in town until 2016.

There is also an annual skirmish that takes place on Kings Highway East in June every year, hosted by the Haddonfield Historical Society.

[141] Their efforts to "annoy" the redcoats[142] worked as Gen. Washington defeated the British army at the Battle of Monmouth a month later.

[143] The event includes many additional activities such as a yelling contest, colonial dancing, pillory prisoners, character reenactors, and tours of Historic Haddonfield.

[148] The New Jersey Turnpike briefly cross through the borough, but the closest exit is Interchange 3 in Bellmawr / Runnemede.
