Stenocarpus is a genus of about 25 species of woody trees or shrubs, constituting part of the plant family Proteaceae.
In Australia, 10 species are known growing naturally in rainforests of eastern New South Wales and Queensland and in the northern monsoonal forests of Queensland, Northern Territory, and Western Australia. Two of these eastern Australia species also grow naturally in New Guinea and one in the Aru Islands, Moluccas.
The greatest species diversity occurs in New Caledonia, where 12 endemic species are known.
By far the most well known in Australia is Stenocarpus sinuatus, the Queensland firewheel tree, which is commonly used as a street or garden tree on the east coast.
