The New Jersey Naval Museum (NJNM) was a museum located along the Hackensack River in Hackensack in Bergen County, New Jersey, United States. Its mission was dedicated to the state's Navy heritage and naval history in general. The prominent element in the collection was the USS Ling (SS-297), a 312-foot (95 m) long Balao-class submarine of World War II. The museum land has since been sold for redevelopment, however the USS Ling remains grounded in the river, with an uncertain future. Efforts have been made since 2007 to find a new home for the Ling. In 2019, the began a campaign to attempt to relocate the ship to the Ohio River.
