Gunbar is in the Riverina district of south-western New South Wales in Australia, on a wide bend of the Mid-Western Highway between Goolgowi and Hay. It is part of the Carrathool Shire local government area, administered from Goolgowi. At the 2006 census, Gunbar had a population of 97 people.
In its heyday Gunbar was a village which served as the hub of the surrounding pastoral properties and the community of selectors that had settled in the district from the 1870s onwards. Nowadays the Gunbar community consists of those who live and work on district farming properties. The Presbyterian church, still used for worship, stands on an elevated position overlooking the original village-site, where the corrugated-iron Community Hall is the only other major building that remains. Scattered peppercorn trees give further evidence of the village that once stood there. Gunbar cemetery is located just over a mile away, nearby to the site of the old government-surveyed township (NNE of the original village).
