'''Algodonite''' is a copper arsenide mineral with formula: Cu<sub>6</sub>As. It is a gray white metallic mineral crystallizing in the hexagonal system. It has a Mohs hardness of 4 and a specific gravity of 8.38 – 8.72.

It was first described in 1857 from the Algodones silver mine, Coquimbo, Chile.
