The current Keansburg Police Department was created under an ordinance adopted in November 1926 which consisted of five members. The area known as Keansburg was under the authority of a Police Marshal prior to 1926. Before 1917, the area was patrolled by both Raritan Township and Middletown Township. The borough's first Police Marshal was James Gilligan, who was appointed in 1917 who served until his retirement in August 1943. The Chief of Police is James K. Pigott, who succeeded Raymond O'Hare who served from 1985 - 2012.
