Atacamite is a mineral found originally in the desert of Atacama Desert, Chile, and named by D. de Gallizen in 1801. It is a copper(II) chloride hydroxide, with formula Cu₂Cl(OH)₃.

Its colour is various shades of green, usually dark. Atacamite is a comparatively rare mineral, formed from primary copper minerals in the oxidation or weathering zone of arid climates.

Atacamite is polymorphous with Botallackite.
