Lesueur Conservation Park, formerly the Cape Hart Conservation Park, is a nature reserve on Kangaroo Island, South Australia. It was dedicated in 1971 to conserve a representative example of the soils and coastal vegetation of the southern part of the eastern end of the island. It is characterised by impressive coastal cliff scenery. Its name was changed on 28 March 2002 in honour of Charles Alexandre Lesueur, a member of the Baudin expedition to Australia.
The park has an area of 1,369 hectares (3,380 acres) with 2 km of coastline. It lies about 4.5 kilometres (2.8 mi) south-west of Cape Willoughby, the easternmost point of Kangaroo Island, and 15 km south-east of the town of Penneshaw. Geologically, the park lies on sandstone, with granite boulders along the coast. The vegetation is mainly an open scrub of Eucalyptus diversifolia (Soap Mallee), with low shrubland containing Melaleuca gibbosa on the coastal cliffs. There are patches of Eucalyptus cneorifolia / Melaleuca uncinata open heath and Allocasuarina verticillata low open forest. Kangaroo Island Kangaroos and Tammar Wallabies inhabit the park and Australian Sea Lions frequent the coast.
