Fairmount was a township that existed in Essex County, New Jersey, United States, from 1862 to 1863.
Fairmount was incorporated as a township by an Act of the New Jersey Legislature on March 11, 1862, from portions of Caldwell Township (now Fairfield Township), Livingston Township and Orange Township.[1]
Fairmount lasted until April 10, 1863, shortly after its first anniversary, when it was absorbed into the newly-created West Orange Township.[1][2]
