The Bass Pyramid, part of the Furneaux Group, is a small, two sectioned oval, steep-sided 100-square-metre (1,100 sq ft) unpopulated granite island, located in Bass Strait, lying north of the Flinders Island and south of the Kent Group, in Tasmania, Australia. A rock bridge connects the two sections.
Recorded breeding seabird and wader species include fairy prion, common diving-petrel, Pacific gull, silver gull, Australasian gannet and sooty oystercatcher. It is also a haul-out site for Australian fur seals. The seals were hunted here in the 19th century. The dangers of the site resulted in at least three sealers losing their lives here.
