Norfolk Island pine, Araucaria heterophylla, is endemic specifically to Norfolk Island — a small, subtropical island in the Pacific Ocean roughly 1,440 kilometres east of Sydney, Australia, situated between New Zealand and New Caledonia — along with the nearby, much smaller Phillip Island. Despite its common name and pine-like appearance, it isn't a true pine at all; true pines belong to the genus Pinus within the family Pinaceae, while Norfolk Island pine belongs instead to Araucariaceae, an ancient and now geographically fragmented conifer family that was once far more widespread across the globe before going extinct throughout the entire Northern Hemisphere, surviving today only in scattered pockets of the Southern Hemisphere. Its closest well-known relative among common ornamental plants is the monkey puzzle tree, another member of the same ancient family.

The species has a well-documented history of European discovery tied directly to one of history's most famous explorers: Captain James Cook became the first European known to sight Norfolk Island, in 1774, during his second voyage to the South Pacific aboard HMS Resolution. Cook noted the presence of large numbers of tall, remarkably straight trees and speculated they might prove useful as masts and yards for sailing ships, given their impressive height and form. Subsequent testing found the wood unsuitable for that specific naval purpose, though it did prove useful for other, more modest applications over the following decades. Botanically, the species was initially described in 1788 by the French naturalist Jean-Baptiste Lamarck, based on specimens collected during Cook's expedition, under the name Araucaria excelsa; it was later reclassified and given its current accepted name, Araucaria heterophylla, by the botanist Adolphe Brongniart in 1842, with the species epithet "heterophylla" — meaning "different leaves" — referencing the genuinely distinct leaf shapes the tree displays at different stages of its growth, from soft and needle-like on young plants to more scale-like and tightly overlapping on mature growth. Adding a further layer of common confusion, plants labeled and sold as 'Norfolk Island pine' in some markets, particularly in Hawaii and on the US mainland, are occasionally actually a closely related but genuinely distinct species, Araucaria columnaris (Cook pine), the two having been historically confused with one another after introduction; the two can be distinguished by growth habit, with true Norfolk Island pine displaying a more open, pyramidal crown with straight, ascending branches, while Cook pine typically shows a narrower, more columnar, often visibly leaning trunk with densely grouped, drooping branches.
