What is now Cedar Grove was originally incorporated by an act of the New Jersey Legislature as the Township of Verona on February 7, 1892, from portions of Caldwell Township. Portions of the township were taken to create Verona borough, based on the results of a referendum held on April 30, 1907. On April 9, 1908, the name was formally changed to Cedar Grove. The township's name derives from the Eastern Red Cedar trees that once covered its valley and hillsides.
