Wenonah is a Borough in Gloucester County, New Jersey, United States. As of the 2000 United States Census, the borough population was 2,317. It is located approximately 10 miles south of Philadelphia, Pennsylvania.
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.
Wenonah was founded in 1871 by Philadelphia businessmen as a country resort. Its location along the Mantua Creek and on the West Jersey Railroad made it a convenient get-away. 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.
