Rochelle Park is a township in Bergen County, New Jersey, United States. As of the United States 2000 Census, the township population was 5,528.
What is now Rochelle Park was incorporated as Midland Township on March 7, 1871, from portions of New Barbadoes Township. Rochelle Park was formed as a township by an Act of the New Jersey Legislature on November 5, 1929, replacing Midland Township, based on the results of a referendum held on that same day that passed by a 503-69 margin. The main impetus behind the change in name was to avoid confusion with the nearby community of Midland Park.
