Williamstown is a census-designated place in Monroe Township, Gloucester County, in South Jersey, roughly midway between Camden and Atlantic City along the Route 322 corridor. The area is primarily residential, with development that has expanded substantially over the past two decades as the Philadelphia suburbs pushed into central Gloucester County.

Gloucester County’s craft beverage scene extends into the Monroe Township area, with brewery taprooms and a small number of farm wineries serving both the growing residential population and visitors traveling the Atlantic City Expressway corridor. Williamstown sits near the boundary of Gloucester and Atlantic Counties, placing it within reach of the broader South Jersey craft beverage geography that includes options in Atlantic County to the east and the more rural Gloucester County agricultural areas to the north and west. Visitors coming from the Philadelphia suburbs will find Williamstown accessible via Route 42 and the Atlantic City Expressway, and the area offers a practical stopping point on a South Jersey craft beverage route between Camden and the Shore.
