Springfield Township is a township in Union County, in the U.S. state of New Jersey. The township is located on a ridge in northern-central New Jersey, within the Raritan Valley and Rahway Valley regions in the New York metropolitan area. As of the 2020 United States census, the township's population was 17,178, the highest recorded at any decennial census, an increase of 1,361 (+8.6%) from the 2010 census count of 15,817, which in turn reflected an increase of 1,388 (+9.6%) from the 14,429 counted in the 2000 census.

Springfield was formed as a township on April 14, 1794, from portions of Elizabeth Township and Newark Township, while the area was still part of Essex County, and was incorporated as one of New Jersey's first 104 townships by an act of the New Jersey Legislature on February 21, 1798. It became part of the newly formed Union County on March 19, 1857, with portions remaining in Essex County used to create Millburn. Other portions of the township have been taken to form New Providence Township (November 8, 1809, now known as Berkeley Heights), Livingston (February 5, 1813), Summit (March 23, 1869) and Cranford (March 14, 1871). The township's name derives from springs and brooks in the area.
