Millstone is a borough in Somerset County, in the U.S. state of New Jersey. The borough was originally known as Somerset Courthouse and was the county seat. As of the 2020 United States census, the borough's population was 448, an increase of 30 (+7.2%) from the 2010 census count of 418, which in turn reflected an increase of 8 (+2.0%) from the 410 counted in the 2000 census.

Millstone was incorporated as a borough by an act of the New Jersey Legislature on May 14, 1894, from portions of Hillsborough Township, based on the results of a referendum held that day. The borough was reincorporated on March 12, 1928. The borough was named for the Millstone River (a major tributary of the Raritan River), whose name derives from an incident in which a millstone was dropped into it.

A historic district in Millstone, including 58 buildings, was added to the National Register of Historic Places in 1976. The borough possesses a military significance for 1700–1749, 1750–1799, 1850–1874.

New Jersey Monthly magazine ranked Millstone as its 7th best place to live in its 2008 rankings of the "Best Places To Live" in New Jersey.
