Wenonah was established as a Borough by an act of the New Jersey Legislature on March 10, 1883, from portions of Deptford Township, based on the results of a referendum that was held two days earlier. The borough was named for the mother of Hiawatha in Henry Wadsworth Longfellow's work The Song of Hiawatha.
It is a dry town, where alcohol cannot be sold.
Wenonah was founded in 1871 by Philadelphia businessmen as a country resort, drawn by its location along the Mantua Creek and on the West Jersey Railroad. Over the next 40 years, numerous dams were installed to create recreational lakes. From 1902 until the Great Depression, Wenonah Military Academy, a private military school, trained cadets there.
Throughout its history, Wenonah has been almost exclusively a residential area. Over 21% of the borough's land area is conservation land, which is protected by ordinance from development. There are more than 6 miles (9.7 km) of hiking trails are threaded around lakes and alongside waterways in these conserved areas.
Wenonah is a close-knit community with holiday events every season. Halloween brings the Wenonah Police Station to set up their "Halloween in the Park", a display of inflatable Halloween-themed lit decorations.
