Mantoloking was incorporated as a borough on April 10, 1911, after separating from Brick Township. The name "Mantoloking" is derived from a Native American term meaning "land of sand." In 1846, the area was the site of the tragic wreck of the John Minturn, a three-masted packet ship caught in a gale off the coast, leading to the loss of 38 lives. This disaster contributed to the establishment of the United States Life-Saving Service, a precursor to the modern Coast Guard.
