The Bass Pyramid, part of the Furneaux Group, is a small, two sectioned oval, steep-sided {{convert|100|m2|adj=on}} unpopulated granite island, located in Bass Strait, lying north of the Flinders Island and south of the Kent Group, in Tasmania, Australia.{{Gazetteer of Australia |name=Bass Pyramid(TAS) |feature=TAS09652 }} A rock bridge connects the two sections.

The island was used intermittently from the 1940s until 1988 as a bombing and shelling target by the Australian airforce and navy. On 5 April 1978 the island was proclaimed part of a nature reserve.

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.Brothers, Nigel; Pemberton, David; Pryor, Helen; & Halley, Vanessa. (2001). Tasmania’s Offshore Islands: seabirds and other natural features. Tasmanian Museum and Art Gallery: Hobart. {{ISBN|0-7246-4816-X}} The seals were hunted here in the 19th century.Parry Kostoglou (1996), Sealing in Tasmania, Hobart, Tasmanian Parks and Wildlife Service, p.117-8. The dangers of the site resulted in at least three sealers losing their lives here.Kostoglou, p.118.
