Mount Torrens is a small town in the eastern Adelaide Hills region of South Australia, 46 kilometres (29 miles) east-north-east of the state capital, Adelaide and 8 kilometres (5 miles) east of Lobethal.

The first Europeans to ascend it, on 25 January 1838, were the exploration party of Dr George Imlay and John Hill, but they did not name it.

Then known as Barton Springs, it incorporated a farmhouse, smithy, stables and the Cornish Arms inn.

The town proper was laid out in 1853 to serve the River Murray trade at Mannum and a nearby copper mine.
