Harden-Murrumburrah is a township and community in Hilltops Council and is located in the South West Slopes region of New South Wales in Australia and is adjacent to both the Canberra region of the Australian Capital Territory and the Riverina Region in the southwest area of NSW. The town is a twin town between Harden and Murrumburrah (which is noted as one of the earliest settlements in the southwest of New South Wales).
The town is traversed by the Burley Griffin Way, the major link from and between the Riverina and the Hume Highway near Yass, and ultimately Sydney, Canberra and the coast. Cunningham Creek runs along the edge of the town.
The Olympic Highway traverses the western end of the shire and is the major link through the central west to the Blue Mountains and from there to the Sydney region.
Harden is 3½ hours away by road from Sydney, and 1½ hours from Canberra and Wagga Wagga. The shire is accessible via the XPT passenger rail service.
