A humpy, also known as a gunyah,^[1][2][3][4] wurley, wurly, wurlie, mia-mia, wiltija, is a small, temporary shelter, traditionally used by Australian Aboriginal people. These impermanent dwellings, made of branches and bark, are sometimes called a lean-to, since they often rely on a standing tree for support.

The word humpy comes from the Jagera language (a Murri people from Coorparoo in Brisbane); other language groups would have different names for the structure. In South Australia, such a shelter is known as a "wurley" (also spelled "wurlie"), possibly from the Kaurna language.^[5][6][7] They are called wiltjas in Pitjantjatjara and Yankunytjatjara languages, mia-mia in Wadawurrung language.^[8][9]

They were temporary shelters made of bark, branches, leaves and grass used by Indigenous Australians.^[10] Both names were adopted by early white settlers, and now form part of the Australian lexicon. The use of the term appears to have broadened in later usage to include any temporary building made from any available materials, including canvas, flattened metal drums, and sheets of corrugated iron.
