The South Tasman Rise is an area of seafloor that lies 550 km south of Hobart, Tasmania in the Southern Ocean where water depths are about 1500 metres. The South Tasman Rise is also known as the Tasmania Ridge or South Tasmania Ridge. The rise forms a northern extension from the Macquarie-Balleny Ridge which extends to the subantarctic Balleny Islands.

The rise forms a sector of an international fishery managed by Australia and New Zealand. This area of the seafloor is slated for exploration of offshore oil reserves beyond 2010.

To east of the rise is the Tasman Basin, while the South Australian Basin extends westwards, south of the Great Australian Bight.
