Freehold Township was first formed on October 31, 1693, and was incorporated as a township by an Act of the New Jersey Legislature on February 21, 1798. Portions of Freehold Township were taken to form Upper Freehold Township (c. 1731), so some wills and official records following the split referred to "Lower Freehold Township" although the official name has always been Freehold Township. Additional portions formed Millstone Township (February 28, 1844), Jackson Township (March 6, 1844), Atlantic Township (February 18, 1847; now Colts Neck Township), Marlboro Township (February 17, 1848) and Manalapan Township (March 9, 1848). Freehold town was formed within the township on March 25, 1869, and formally separated when it was reconstituted as a borough on April 15, 1919, including additional portions of the township.
