Bergen Neck is a peninsula in the United States, located between the Upper New York Bay and the Newark Bay in the Hudson County, New Jersey municipalities of Bayonne and Jersey City. Its southernmost tip, Bergen Point, is separated from Staten Island by the Kill van Kull, which is crossed by the Bayonne Bridge. It was likely first called so in the 17th century by the first Dutch and English speaking settlers to the region between the bays and northward along the Hudson River and Hackensack River. Though now part of Hudson County, the area was part of Bergen County from its creation in 1683 until Hudson County was created in 1840, and was part of Bergen Township, which lasted until 1862.
It was first named Oyster Island by the Dutch, who at first thought it was an island, and for a brief period after the British takeover of New Netherland in 1674 was called Old Hackensack Neck. During the American Revolution British maps showed it as Barren Neck. Bergen Neck is rarely used, occasionally replaced by the terms such as Bayonne Peninsula, Hudson Peninsula, South Hudson. It gave its name to a fort during the American Revolution, which was built in 1776, occupied by the British in 1777, and demolished in September 1782. (In British hands the fort was renamed for Oliver De Lancey, Sr. as Fort Delancey.)It still lends its name to First Reformed Dutch Church of Bergen Neck in Bayonne.
