Belleville is a township in Essex County, in the U.S. state of New Jersey. As of the 2020 United States census, the township's population was 38,222. Originally known as "Second River" or "Washington", the inhabitants renamed the settlement "Belleville" in 1797. Belleville was originally incorporated as a township by an act of the New Jersey Legislature on April 8, 1839, from portions of Bloomfield. Portions of the township were taken to create Woodside Township and Franklin Township. The independent municipality of Belleville city was created within the township on March 27, 1874, and was dissolved on February 22, 1876. On November 16, 1910, Belleville was reincorporated as a town, based on the results of a referendum held eight days earlier.
