Gunning is a small town on the Old Hume Highway, between Goulburn and Yass in the Southern Tablelands of New South Wales, Australia, about 260 km south-west of Sydney and 75 km north of the national capital, Canberra. Nearby towns and cities are Cullerin, Gundaroo, Dalton, Yass, Murrumbateman and Goulburn.

The Old Hume Highway, an urban and rural road, may be described as any part of an earlier route of the Hume Highway, which traverses Victoria and New South Wales between the cities of Sydney and Melbourne in Australia. In some places, the highway has been deviated several times since the first rough track was made between Sydney and Melbourne in November 1842.
