Changoite is a rare zinc sulfate mineral with the formula Na2Zn(SO4)2·4H2O.

[5][3] Chagoite was discovered in the San Francisco Mine near Sierra Gorda, Antofagasta, Chile.

[5] In terms of chemistry changoite is somewhat similar to gordaite.

[4] Traces of magnesium and calcium in changoite are negligible.

[4] Minerals associating with changoite are gypsum, zinc-bearing paratacamite, and thénardite.
