Wollemia is a genus of coniferous trees in the family Araucariaceae, endemic to Australia. It represents only one of three living genera in the family, alongside Araucaria and Agathis. The genus only has a single known species, Wollemia nobilis, which was discovered in 1994 in a temperate rainforest wilderness area of the Wollemi National Park in New South Wales. It was growing in a remote series of narrow, steep-sided, sandstone gorges 150 km (93 mi) north-west of Sydney. The genus is named after the National Park.[2]

In both botanical and popular literature, the tree has been almost universally referred to as the Wollemi pine (/ˈwɒləmaɪ/),[3] although it is not a true pine (genus Pinus), nor a member of the pine family (Pinaceae).
The Wollemi pine is classified as critically endangered (CR) on the IUCN's Red List,[1] and is legally protected in Australia.[4] After it was discovered that the trees could be successfully cloned, new trees were potted up in the Botanic Gardens of Sydney and Mount Annan and planted as far away as the Humboldt Botanical Garden near Eureka, California.[5]
A Recovery Plan has been drawn up, outlining strategies for the management of this fragile population. The overall objective is to ensure that the species remains viable in the long term.[4] Australian prime ministers and foreign affairs ministers have presented Wollemi pines to various dignitaries around the world.[6]
Although often described as a "living fossil", there are no unambiguous fossils of Wollemia and potential fossil records of it have been considered uncertain.[7]
