Cape Sorell is a headland located in the Southern Ocean outside Macquarie Harbour on the West Coast of Tasmania, Australia.

Cape Sorrell is named in honour of William Sorell, Lieutenant-Governor of Tasmania from 1817 to 1824.

The lighthouse is located approximately 12 kilometres (7.5 mi) southwest of Strahan.

It was used to move rock from quarries for the construction and maintenance of the Macquarie Heads breakwater.

The Cape Sorell Waverider Buoy, also known as Captain Fathom as named by the listeners of ABC Radio, Tasmania during the May 2015 to mark the centenary of the Bureau of Meteorology,[3] is a swell-measuring buoy located west of Cape Sorell some 10 kilometres (6.2 mi) west of Ocean Beach (42°12′S 145°03′E / 42.200°S 145.050°E / -42.200; 145.050).
