Zeunerite is a green copper uranium arsenate mineral with formula Cu(UO2)2(AsO4)2·(10-16)H2O.

The associated mineral metazeunerite is a dehydration product of zeunerite.

Zeunerite occurs as a secondary mineral in the oxidized weathering zone of hydrothermal uranium ore deposits which contain arsenic.

Olivenite, mansfieldite, scorodite, azurite and malachite are found in association with zeunerite.

[2] It was first described in 1872 for an occurrence in the Schneeberg District, Ore Mountains, Saxony, Germany.
