The wild orange is an Australian native plant found in dry inland areas of Australia. Its scientific name is Capparis mitchellii. It is not related to oranges, nor to the Osage-orange which is known as "wild orange" in North America, but to capers.

Used by Aboriginal Australians as bush tucker long before European settlement in Australia, the fruit is a good source of vitamin C and may be enjoyed raw or in sweet and savoury dishes.
