Cape Mentelle is a limestone headland on the Indian Ocean coast of south-western Western Australia. It is within the Leeuwin-Naturaliste National Park, just north of the mouth of the Margaret River and west of the town of Margaret River. It lies on the Leeuwin-Naturaliste Ridge, halfway between Cape Naturaliste to the north, and Cape Leeuwin to the south, on the route of the Cape to Cape walking track.
The cape was named on 4 February 1803 by French navigator Nicolas Baudin, on his expedition to Australia, after Edme Mentelle (1730-1815), a French geographer, historian and cartographer.[1] It has given its name to a well known Margaret River winery, Cape Mentelle Vineyards.
