Dalmeny is a town on the south coast of New South Wales, Australia, approximately seven kilometres north of Narooma. At the 2011 census, Dalmeny had a population of 1,932 people.
Dalmeny is a mainly residential area, with the town built upon headlands looking over the Pacific Ocean to the south, and the shore of Lake Mumumga, a coastal lagoon, to the north. Due to its location, Dalmeny is a reasonably popular camping area, with a large camping ground located in the centre of town overlooking the southern end of Brou Beach (commonly called Dalmeny Beach, despite this technically being the next beach south). Despite the town's small and mainly residential nature, the town has a small shopping district in the centre of town, an industrial area to its north-west, and two retirement and aged-care facilities, as well as a bowling club with 4 greens and a small restaurant.
There are many walking and cycling paths through Dalmeny, some along the coastline. Bushwalking is possible in some areas of the Eurobodalla National Park. Dalmeny also has many public boat ramps, picnic spots and lookouts.
