Milltown is a small borough in Middlesex County, New Jersey, set in the Raritan Valley with Lawrence Brook, a tributary of the Raritan River, flowing through its center. The community of about 7,000 people occupies a compact area of roughly 1.6 square miles, giving it a walkable, close-knit character that contrasts with the larger surrounding townships of East Brunswick and North Brunswick. The borough's origins are tied to the brook that divides it. Early settler Jacob I. Bergen built a grist mill along Lawrence Brook in 1816, and the settlement that grew around it was known as Bergen's Mills. Milltown was incorporated as a borough in 1889 from portions of North Brunswick, with a piece of East Brunswick added in 1902. The Lawrence Brook Mill, formerly Bergen's Mill, survives as a reminder of that industrial beginning. Education is provided by the Milltown Public Schools, a two-school district serving grades Pre-K through 8 with roughly 800 students, while high school students attend Spotswood High School through a send-receive relationship with the Spotswood Public Schools. The district's small size keeps the schools closely tied to the community. Milltown's location is one of its chief advantages. The borough sits a short drive from New Brunswick and Rutgers University, and the surrounding Middlesex County network of Route 1, Route 18, and the New Jersey Turnpike connects it to the broader region, including commuter rail at New Brunswick on the Northeast Corridor. For homebuyers, Milltown offers an affordable, walkable, family-oriented small town with convenient access to the employment, education, and cultural anchors of central New Jersey.
