Araucaria is a genus of coniferous trees. There are 19 species in the genus, with a highly disjunct distribution in New Caledonia (where 13 species are endemic), Norfolk Island, eastern Australia, New Guinea, Argentina, Chile, and southern Brazil.
Fossil evidence indicates that ancestral araucaria forests resembling the present-day Monkey Puzzle date back to the age of dinosaurs.
Some of the species are relatively common in cultivation because of their distinctive, formal symmetrical growth habit. Several species are economically important for timber production and the edible seeds.
