Lincoln National Park is a protected area in the Australian state of South Australia located about 249 kilometres (155 mi) west of the state capital of Adelaide and about 9.5 kilometres (5.9 mi) south of the municipal seat of Port Lincoln.

Lincoln National Park includes the following islands which are located in the waters adjoining the Jussieu Peninsula:[6]: 2 The national park is classified as an IUCN category II protected area[1] On 28 August 1941, land in sections 2, 5, 6, and 13 in the cadastral unit of the Hundred of Flinders was dedicated under the Crown Lands Act 1929 as a Flora and Fauna Reserve.

"[8] In the years 1972–1992, the national park increased in size by the addition of land at Stamford Hill (whose original Barngarla name was Gaidyaba[9]: 78 ), Cape Donington, Wanna and many of the islands adjoining the coast of the Jussieu Peninsula.

Archaeological digs have found sites of stone working, including fish traps, and middens throughout the national park.

Other industries that occurred in the early parts of European settlement were woodcutting, grazing and guano mining.

Feral foxes were once common in the national park, endangering the existence of many native animals, however after an extensive baiting and culling program, their numbers have diminished.

With the reduction in fox numbers, a rebound in goanna and bush stone curlew populations have been recorded.

Migratory birds such as stints and sandpipers spend summer in the national park as part of their seasonal migrations from places as distant as the Arctic Circle and Siberia.

Southern right whales are visible in the water surrounding the national park during their seasonal migrations between July and November and Australian sea lions can be seen on rocks and small islands off the coast.

The national park hosts a range of activities including bushwalking, four-wheel driving, camping, snorkelling, scuba diving, swimming and fishing.
