Agathis robusta, commonly known as Dundathu pine, kauri pine, Queensland kauri (pine), Australian kauri (pine) or smooth-barked kauri, is a coniferous tree in the family Araucariaceae. Although sometimes called a pine it is not a true pine, having leaves rather than needles. It has a disjunct distribution, occurring in eastern New Guinea and New Britain in Papua New Guinea and Queensland, Australia.

Araucariaceae – also known as araucarians – is a family of coniferous trees, with three living genera, Araucaria, Agathis, and Wollemia. While the family was distributed globally during the Jurassic and Cretaceous periods, in their native distribution they are now largely confined to the Southern Hemisphere, except for a few species of Agathis in Southeast Asia.
