Milltown was incorporated as a borough by an act of the New Jersey Legislature on January 29, 1889, from portions of North Brunswick, based on the results of a referendum held three days earlier. The borough was reincorporated by resolution of the borough council on May 2, 1896. A portion of East Brunswick Township was annexed in 1902.[22] Originally known as Bergen's Mill, named for Jacob I. Bergen who owned the grist mill,[23] the name is believed to have become "Milltown" from residents "going to the mill in town".[24]

John Ford advances Meyer the money to rebuild. It is in this period of time that the name Bergen's Mill begins to be replaced with Milltown, most likely stemming from people saying they are 'going to the mill in town.'"

"For any of you who have ever lain awake at night asking: Where, oh where is the statistical center of New Jersey, there really is an answer. Nenninger Lane, East Brunswick.... Over the last several decades, New Jersey’s statistical center has gradually crept its way south and west along the New Jersey Turnpike as growth in the southern and western portions of the state has outpaced the north.... Ten years ago, it was at an intersection in Milltown, about a tenth of a mile from the Turnpike and a few paces south of a Home Depot."
