Hopatcong ( ) is a borough in Sussex County, in the U.S. state of New Jersey. As of the 2020 United States census, the borough's population was 14,362.

History The town of Hopatcong has a rich history, given its relationship with New York City. It borders Lake Hopatcong, a partially man-made lake that is now a source of much recreation and desirable real estate, and is the biggest lake in New Jersey. The community, west of New York City, began as a summer getaway for the wealthy in NYC who primarily sought access to the lake. An amusement park, called "Bertrand's Island", sprang up and was accessible via the lake, trolley or by car through Mount Arlington. The construction of Interstate 80, a highway that stretches from Teaneck, New Jersey, all the way across the country to San Francisco, California, triggered rapid growth in New York City's suburbs and led to Hopatcong becoming a permanent residential community. The area had been called "Brookland" in the 19th century and the lake that was expanded to become Lake Hopatcong had been known as "Great Pond" or "Brookland Pond". Variant names: Brookland, Brooklyn Variant names: Brooklyn Pond, Great Pond During the 1830s, the name of the community had been modified to "Brooklyn", to match the spelling of the city on New York's Long Island.Balston, Mottel. A History of Landing, Morris County, New Jersey, LandingNewJersey.com. Accessed May 19, 2008. Hopatcong was originally established as the Town of Brooklyn on April 2, 1898, from portions of Byram Township. On March 22, 1901, the Borough of Hopatcong replaced Brooklyn.Snyder, John P.

In 1922, residents of Byram Cove, Northwood, and other areas to the west of the original land area of the borough, voted to leave Byram Township and join Hopatcong, leaving the Borough with its current borders.Historical Information, Borough of Hopatcong. Accessed November 6, 2017. "The newly formed Borough stretched from the Musconetcong River, in what is today Hopatcong State Park, to the southern shore of Byram Cove.... This left the areas of Byram Cove and Northwood, as well as significant lands to the west (including Bear Pond), still in Byram Township. As these locales began to develop, their residents wished to join Hopatcong, which had shared interests. In 1922, the local population of these areas voted to join Hopatcong and the Borough grew to the borders we know today."

While the origin of the borough's name is unclear, it is said to derive from Native American phrases variously meaning "stone over water" or "pipestone", among other variations.Hutchinson, Viola L. The Origin of New Jersey Place Names, New Jersey Public Library Commission, May 1945. Accessed September 2, 2015.Gannett, Henry. The Origin of Certain Place Names in the United States, p. 138.

The borough council includes six members elected to serve three-year terms on a staggered basis, with two seats coming up for election each year in a three-year cycle.2012 New Jersey Legislative District Data Book, Rutgers University Edward J. Bloustein School of Planning and Public Policy, March 2013, p. 53.
