Isle of the Dead, Historic cemetery islet near Port Arthur, Australia.

Isle of the Dead is a one-hectare island in Carnarvon Bay, about 700 metres from Point Puer off the Tasman Peninsula. Its southern end holds unmarked convict graves, while the north-western corner has about eighty headstones and footstones cut by convict stonemasons. An Aboriginal shell midden with shells, charcoal and ash lies beneath an overhanging cliff.

The island served as a burial ground from 1833 to 1877 for roughly 1,000 deceased from the Port Arthur penal settlement, including prisoners and officials. This period matched the growth and decline of the prison itself.

The cemetery layout shows class differences from colonial times, with separate sections for prisoners buried without names and officials whose graves have carved stones.

The island lies in Carnarvon Bay, about 700 metres from Point Puer and 1.2 km from Mason Cove, and can be reached only by boat; the Port Arthur Historic Site runs guided ferry tours. Driving from Hobart via the Tasman and Arthur Highways takes around 80 minutes.

The island's Aboriginal shell midden, sheltered under an overhanging cliff, holds shells, charcoal and ash from camps where the Pydairrerme people gathered abalone and mussels before the 1830s. It is protected as an Aboriginal relic under the Aboriginal Heritage Act 1975.
