Vivonne Bay Conservation Park is a nature reserve on the south coast of Kangaroo Island, South Australia. It was dedicated in 1971 to conserve coastal country containing vegetation not already protected in Kelly Hill Conservation Park.
The park has an area of 887 ha, stretching from Point Ellen, at the western end of Vivonne Bay, south-westwards along the coast for about 5 km, extending inland for 3 km. The vegetation is mainly open scrub and open heath dominated by Eucalyptus diversifolia and E. rugosa, with low Calocephalus brownii shrubland on the coastal dunes and cliffs.
