Phoracantha species are native to Australia and New Guinea, though some species have been introduced to parts of Africa, Europe, North America, and South America. Most Phoracantha species are native to southern Australia, with a smaller proportion of species native to northern Australia and/or New Guinea. The genus is represented in every Australian state and is mostly distributed along the coast, with only one species, P. tuberalis, restricted to central Australia.
