Milltown is a borough in Middlesex County, in the U.S. state of New Jersey. The borough is nestled within the heart of the Raritan Valley region, with Lawrence Brook (a Raritan river tributary) flowing through the center of the community. As of the 2020 United States census, the borough's population was 7,037, an increase of 144 (+2.1%) from the 2010 census count of 6,893, which in turn reflected a decrease of 107 (−1.5%) from the 7,000 counted in the 2000 census.

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. Originally known as Bergen's Mill, named for Jacob I. Bergen who owned the grist mill, the name is believed to have become "Milltown" from residents "going to the mill in town".

As of the 2000 Census, the center of population for New Jersey was located in Milltown, at Milltown Road, just east of the New Jersey Turnpike (see map of location). Based on the results of the 2010 census, the center of population had shifted to East Brunswick.
