The Argan (Argania spinosa) is a species of tree endemic to the calcareous semi-desert Sous valley of southwestern Morocco and to the Algerian region of Tindouf in the western Mediterranean region. It is the sole species in the genus Argania.

In Morocco arganeraie forests now cover some 8,280 kmē and are designated as a UNESCO Biosphere reserve. Their area has shrunk by about 50% over the last 100 years, owing to charcoal-making, grazing, and increasingly intensive cultivation. The best hope for the conservation of the trees may lie in the recent development of a thriving export market for argan oil as a high-value product.

In some parts of Morocco, argan takes the place of the olive as a source of forage, oil, timber and fuel in Berber society. Especially near Essaouira, the argan tree is frequently climbed by goats.
