Eden is a coastal town in the South Coast region of New South Wales, Australia. The town is 478 kilometres (297 mi) south of the state capital Sydney and is the most southerly town in New South Wales, located between Nullica Bay to the south and Calle Calle Bay, the northern reach of Twofold Bay, and built on undulating land adjacent to the third-deepest natural harbour in the southern hemisphere, and Snug Cove on its western boundary. At the 2016 census, Eden had a population of 3,151.
The eastern coastline has rugged cliffs at the southern end and a wide, sandy surf beach, Aslings Beach, north of the cliffs. The beach ends at the entrance to Lake Curalo, a safe boating inlet of Twofold Bay. Although the urban settlement of Eden commenced in 1843 the settlement was not officially proclaimed as a township until 20 March 1885. The town's main industries include fishing, forestry, and tourism.
