Manchester Township was a Township that was formed on February 7, 1837 within Bergen County, New Jersey, and later split into Passaic County.
As originally constituted, the Township included portions of present day Hawthorne (formed March 24, 1898), Haledon (April 8, 1908), North Haledon, Prospect Park, Totowa and most of the First Ward of Paterson.
With the creation of the Borough of Haledon, Manchester Township was dissolved that same day, April 8, 1908.
