Freycinet Marine Park, Marine protected area off eastern Tasmania, Australia

Freycinet Marine Park is a 57,942 km2 marine protected area off the east coast of Tasmania, reaching the outer limit of Australia's exclusive economic zone in the Tasman Sea. It is the largest reserve in the South-east Commonwealth Marine Reserve Network, covering about 86% of Tasmania's land area. Large offshore seamounts, believed too deep to have been fished, lie within it, and great white sharks forage there.

Freycinet Commonwealth Marine Reserve was established in 2007 as part of the South-east Commonwealth Marine Reserve Network. It covers 57,942 km2, the largest area in that network, roughly 86% of Tasmania's land area, and reaches the outer limit of Australia's exclusive economic zone in the Tasman Sea.

The reserve lies in the Tasman Sea off Tasmania's east coast and reaches the outer limit of Australia's exclusive economic zone. Its name comes from the adjacent Freycinet Peninsula, named after French navigator Louis de Freycinet. Most of the area is IUCN category II, with small coastal zones set aside for recreational and multiple use.

The park is mainly intended for research purposes, but is also accessible to divers and nature observers depending on conditions in different zones. Visitors should note that access depends on private boats or organized scientific expeditions.
