The Nut is a volcanic plug near the town of Stanley, Tasmania.

[7] The Nut's geological characteristics have important implications for the local environment providing unique habitats for flora and fauna, including breeding sites for various bird species.

[8] The basaltic rocks weather to form fertile red soil, which is valuable for agriculture in northwestern Tasmania.

[9][4] The European discovery of the Nut was made by George Bass and Matthew Flinders when they circumnavigated Tasmania in the sloop Norfolk.

[4][1] The origins of its name are speculated to be from the Tasmanian Aboriginal name, "munatrik" (moo-nut-re-ker), or because explosives were unable to dent it during the construction of a breakwater.
