'''Cabalzarite''' is a rare arsenate mineral with the chemical formula {{chem|Ca|(Mg|,Al|,Fe|3+|)|2|[As|O|4|]|2|•2(H|2|O|,O|H)}}. It is a member of the tsumcorite group. It crystallizes in the monoclinic system and typically occurs as clusters of crystals or granular aggregates.<ref name=Webmin/><ref name=Mindat/>

It was first described for samples from an abandoned manganese mine in Falotta, Graubünden, Switzerland and named for Swiss amateur mineralogist Walter Cabalzar. It was approved as a new mineral by the IMA in 1997. It has also been reported from the Aghbar mine in Ouarzazate Province, Morocco.<ref name=Mindat/> ==References== {{reflist}}
