 Starting in the 1840s, several new municipalities were created from portions of Franklin Township (Pompton Township on April 10, 1797, Hohokus Township (now Mahwah) on April 9, 1849, and Ridgewood Township on March 30, 1876; remaining now the Village of Ridgewood), so that today what is now Wyckoff borders eight different communities.Wyckoff was formed as a township by an act of the New Jersey Legislature on November 2, 1926, replacing Franklin Township, based on the results of a referendum held that day.Portions of Wyckoff were ceded to Midland Park based on the results of a referendum held on June 9, 1931.
