Hamilton Square is an unincorporated community and census-designated place (CDP) located within Hamilton Township, in Mercer County, in the U.S. state of New Jersey, that is the site of a historic colonial village. Until the 2000 census the area was part of the Mercerville-Hamilton Square CDP, which was split into two CDPs as of 2010: Mercerville and Hamilton Square.

Hamilton Square was established in 1692 and was named after Alexander Hamilton in a wave of anti-British feeling at the time of the War of 1812. It previously had been called "Nottingham" after the British town. As of the 2020 census, the CDP's population was 12,679.
