Jacksonville is an unincorporated community located within four municipalities originally in Pequannock Township, in Morris County, in the U.S. state of New Jersey.

In the 19th century, the area known as Jacksonville was wholly located within Pequannock Township.

Upon the creation of the township of Montville in 1867, Jacksonville was split between these two municipalities.

[citation needed] In 1922, the borough of Kinnelon and the borough of Lincoln Park were created out of a portion of Pequannock Township, further splitting Jacksonville into a portion of four municipalities.
