Millstone Township is a township in western Monmouth County, in the U.S. state of New Jersey. The township is located within the Raritan Valley region and is a part of the New York metropolitan area. As of the 2020 United States census, the township's population was 10,376, a decrease of 190 (−1.8%) from the 2010 census count of 10,566, which in turn reflected an increase of 1,596 (+17.8%) from the 8,970 counted in the 2000 census.

The township was named after the Millstone River, a major tributary of the Raritan River, and whose name originated from an incident in which a millstone was dropped into the river. The headwaters for the Millstone River originate in the township.

The township has been ranked as one of the state's highest-income communities. Based on data from the American Community Survey for 2013–2017, Millstone residents had a median household income of $156,891, more than double the statewide median of $76,475 and ranked ninth in the state among municipalities with more than 10,000 residents.
