Brielle is a borough located in southern Monmouth County, New Jersey along the Manasquan River. Brielle was formed as a borough by an act of the New Jersey Legislature on April 10, 1919, from portions of Wall Township, based on the results of a referendum passed on June 3, 1919. The borough was named for Brielle, a town in the Netherlands.
Located at the southeastern corner of Monmouth County, Brielle is bordered to the north and east by the Manasquan, to the west by Brick Township (in Ocean County) and Wall Township and to the south by Point Pleasant and Point Pleasant Beach across the Manasquan River. The borough is primarily a residential community of single homes, with a few condominiums; there are almost no undeveloped lots of land left. There are several businesses located along Union Avenue and Higgins Avenue and some marinas along the Manasquan River. There is also a 140 acres 18 hole golf course called the Manasquan River Golf Club. Manasquan Park is an unincorporated community located within Brielle.
