The Tasman Peninsula is a peninsula located in south-east Tasmania, Australia approximately 75 km (47 mi) by the Arthur Highway, south-east of Hobart.
The Tasman Peninsula lies south and west of Forestier Peninsula to which it connects via an isthmus called Eagle Hawk Neck. This in turn is joined to the rest of Tasmania by an isthmus called East Bay Neck near the town of Dunalley, approximately 60 kilometres (37 mi) by road from Hobart. The peninsula is surrounded by water; to the north by Norfolf Bay, to the northwest by Frederick Henry Bay to the west and south by Storm Bay, and to the east by the Tasman Sea.
The rugged coastline has been the scene of a number of shipwrecks. Two large seagoing steamers have sunk after hitting the Hyppolyte Rock off its east coast - the Tasman in 1883 and the Nord in 1915. Munroe Bight to the north of Cape Pillar is named after the former American barque James Munroe wrecked there in 1850.
The Tasman Peninsula is well known for its rugged eastern coastline, and much of it is now the Tasman National Park At Eagle Hawk Neck are many strange rock formations, including The Devils Kitchen, Tasman's Arch, Blow Hole and the Tessellated Pavement. Further south are the highest sea cliffs in the Southern Hemisphere, rising 300 metres (980 ft) above the Tasman Sea at Cape Pillar.
