Shattuckite is a mineral, a copper silicate hydroxide with formula Cu5(SiO3)4(OH)2. It crystallizes in the orthorhombic - dipyramidal crystal system and usually occurs in a granular massive form and also as fibrous acicular crystals.

Shattuckite is a relatively rare copper silicate mineral. It was first discovered in the copper mines of Bisbee, Arizona, specifically the Shattuck Mine (hence the name). It is a secondary mineral that forms from the alteration of other secondary minerals. At the Shattuck Mine, it forms pseudomorphs after malachite. A pseudomorph is an atom by atom replacement of a crystal structure by another crystal structure, but with little alteration of the outward shape of the original crystal.
