Pompton Lakes was established on February 26, 1895 from portions of Pompton Township, based on the results of a referendum held three days earlier. The borough was named for the Pompton people, a sub-tribe of Native Americans who lived in the area. It was the first borough to be formed in Passaic County as part of the "boroughitis" that had struck the state at the time. Pompton Lakes did not acquire territory from more than one township, which would have entitled the borough to a seat on the County's Board of Chosen Freeholders.
