Freehold Borough was originally incorporated as a town by an act of the New Jersey Legislature on March 25, 1869, from portions within Freehold Township. The town became independent of the township in 1888. On April 15, 1919, Freehold was incorporated as a borough, including all of Freehold and additional portions of Freehold Township, based on the results of a referendum held on July 8, 1919. Additional portions of Freehold Township were annexed on September 7, 1926.
