Mount Franklin, Mountain summit in Brindabella Ranges, Australia.

Mount Franklin is a mountain in the Brindabella Ranges reaching 1,646 metres AHD, with its summit on the Australian Capital Territory side of the ACT–New South Wales border. The peak lies within Bimberi Nature Reserve and Namadgi National Park, and a marked walking trail from Mount Franklin Road leads to the top.

The mountain takes its name from the Franklin family, connected to author Miles Franklin who lived at nearby Brindabella Station in the early twentieth century. This local connection remains part of the place's identity and heritage.

The mountain is named after the family of author Miles Franklin, who spent her childhood at Brindabella station about ten kilometres north on the Goodradigbee River. From the 1930s Australian ski pioneers based themselves on its slopes, and the Canberra Alpine Club cleared runs and improvised tows after its 1938 chalet was built.

A marked trail from Mount Franklin Road leads to the summit without specialised climbing skills. Snow often covers the mountain in winter, and cross-country skiing is possible on Franklin and neighbouring peaks when conditions allow. The ACT/NSW boundary runs through the Franklin Chalet ruin area, and the 2008 shelter gives park managers and rescue teams a base for search operations.

A 2008 shelter designed by University of Adelaide students replaced an older mountain hut destroyed during the 2003 bushfires at this location. The structure now serves as an interpretive center where visitors can learn about the site and its history.
