Montvale was incorporated as a borough on August 31, 1894, from portions of Orvil Township and Washington Township, at the height of the "Boroughitis" craze then sweeping through Bergen County that led to the creation of over two dozen new municipalities in the county in that one year alone. On February 15, 1896, Montvale acquired part of Orvil Township. In 1906, Montvale added further land from Orvil and Washington townships, and in 1912, Montvale added territory from Upper Saddle River. On May 20, 1959, portions of Montvale were passed to River Vale, and on December 9 and 14, 1965, territories were exchanged between Montvale and Upper Saddle River.
