Franklin Township is a township in Somerset County, New Jersey, positioned in the Raritan Valley within the New York metropolitan area. It sits between the cities of New Brunswick and Princeton, placing Rutgers University and Princeton University within a short drive, and it extends across roughly forty-six square miles of central New Jersey. With a population of about 68,400 in the 2020 census, Franklin is one of the largest municipalities in Somerset County and ranks among the most racially and economically diverse communities in the state. The township is not a single town center but a collection of residential sections and small unincorporated hamlets strung along its main roads. The Somerset area, a major commercial and residential corridor, anchors much of the township's retail and housing, while places like Griggstown retain a more rural, canal-side character. Between them, neighborhoods range from densely built streets near the New Brunswick border to tree-lined subdivisions of single-family homes on half-acre and larger lots, along with condominium communities and a growing stock of active-adult developments. Open space defines a significant portion of Franklin's identity. The Six Mile Run Reservoir Site, a 3,037-acre property that was never flooded as a reservoir, is now part of the Delaware & Raritan Canal State Park and offers trails for hiking, biking, and horseback riding. The D&R Canal itself, a historic towpath corridor, runs through the township near Griggstown, linking Franklin to a regional trail network that reaches the Delaware River. Franklin's appeal draws from its combination of suburban housing, deep diversity, and access to both the Princeton-area employment and education corridor and the New Brunswick-to-New York commuter rail network. It suits households seeking a central New Jersey location with substantial open space, a wide range of housing types, and strong highway and rail connections rather than a single walkable downtown.
