Edison is a township located in Middlesex County, in the U.S. state of New Jersey. Situated in Central New Jersey within the core of the state's Raritan Valley region, Edison is a commercial hub (home to Menlo Park Mall and Little India) and is a bedroom community of New York City within the New York metropolitan area. As of the 2020 United States census, the township was the state's sixth-most-populous municipality, with a population of 107,588, an increase of 7,621 (+7.6%) from the 2010 census count of 99,967, which in turn reflected an increase of 2,280 (+2.3%) from the 97,687 counted in the 2000 census. What is now Edison Township was originally incorporated as Raritan Township by an act of the New Jersey Legislature on March 17, 1870, from portions of both Piscataway Township and Woodbridge Township. The township got its original name from the Raritan indigenous people. Portions of the township were taken to form Metuchen on March 20, 1900, and Highland Park on March 15, 1905. The name was officially changed to Edison Township on November 10, 1954, in honor of inventor Thomas Edison, who had his main laboratory in the Menlo Park section of the township.
