Bound Brook is a borough in Somerset County, New Jersey, set along the Raritan River in the county's northeastern corner. First settled in 1681, it is among the oldest communities in the region, and its name reflects the brook that marked the boundary of an early colonial land division. Its population was 11,988 at the 2020 census. The borough occupies a little over 1.6 square miles, making it one of the denser, more walkable towns in Somerset County. Its downtown runs along Main Street and the Raritan River, with a mix of older commercial buildings, apartments, and single-family homes. The surrounding Middlebrook valley is rich in Revolutionary War history: the Continental Army encamped at Middlebrook in the late 1770s, and the Battle of Bound Brook was fought nearby in 1777. Bound Brook is a transportation crossroads. Its NJ Transit Raritan Valley Line station offers direct rail service toward Newark and New York, and buses connect to the Port Authority, making it a practical base for commuters. Interstate 287 and U.S. Route 22 pass just outside town, and the Delaware and Raritan Canal runs along its edge. The Bound Brook School District serves a diverse, multilingual student body from pre-kindergarten through twelfth grade, with campuses in the borough. The Raritan River, while central to the town's identity, has also shaped its history, bringing periodic flooding that the borough and state have worked to manage over the years. For homebuyers, Bound Brook offers affordability, walkability, and rail access uncommon in Somerset County, with the history and density of a true river town.
